Key Points:

It felt like half a nation was pumping the air and singing along to Born To Run as the old rabble-rouser Bruce Springsteen blew through his half-time set at the Superbowl XLIII earlier this month.

For a tech-savvy younger generation, curious as to why someone who looked like their dad had just jumped on to a piano, an obvious reaction would have been to reach for the computer and head to Wikipedia.

Except that they'd have drawn a blank. "Bruce Springsteen. This guy kinda sucks." That was it. A superstar's entire history and discography had been wiped, an encyclopedia page replaced with a blogger's venting. Perhaps it was a Janet Jackson fan who hadn't got over the sanitising of the Superbowl show since that famous wardrobe malfunction.

Later visitors to the page were given a little more to go on. "Bruce Frederick Joseph Springsteen (born September 23, 1949), nicknamed 'The Boss', is a FAG," according to one unhelpful edit. Hit refresh, and suddenly the entire entry appeared to be in Japanese.

Things righted themselves, of course, and quickly. Before the final bars of Glory Days, one of Wikipedia's grown-ups had locked anonymous users out of the editing process and The Boss had returned to form. This has been Wikipedia's organising principle; it is "never wrong for long". Wikipedia was a half-crazed vision when it was launched in January 2001.

At a time when internet sages were discussing how much Britannica could get away with charging for a digital version of its dusty tome, here was an attempt to create an even bigger repository for human knowledge, all of it written and edited - from scratch - by absolutely anyone with a bit of time to spare. Now it is one of the 10 most-visited sites on the web (there are different measures of this list, but Wikipedia itself has agreed that it is the eighth most-visited). Should you need to settle a bar-room row about the scorer of the equaliser in the 1993 FA Cup final, it is to Wikipedia that you instinctively turn.

Increasingly, when you want to find out the latest facts on a developing news story, Wikipedians are updating the site in real time for you, too. As long as you have a critical eye, it cannot be beaten for the bare-bones facts on any subject you can think of - and several million more you can't.

As a result, it is a godsend for stressed researchers and idle students. One New York University professor shakes his head and says he has given up trying to prevent his charges from citing Wikipedia as a source in their essays. Instead, he now spends some time each week checking the accuracy of its entries on the subjects he teaches.

The site has more than justified its founders' faith in the wisdom of crowds. But it has also shown that every crowd has its share of fools and knaves. Vandalism and error are endemic, and it has often driven users to the conclusion that the only way to increase accuracy is to reduce access.

The tensions are not new, but they are growing. Events in recent weeks have seemed to bring Wikipedia to another crossroads. Importantly, the direction it chooses will help shape a long-term financial future for the organisation, which is only now starting to be debated. That battle over Bruce Springsteen, played out over five minutes on one of Wikipedia's 12 million articles, was hardly unique.

At any given moment, there are hundreds of these skirmishes going on. A dip into the methodically kept records of recent edits shows that a kind-hearted Celebrity Big Brother fan had amended British TV presenter Ulrika Jonsson's entry to congratulate her ("You rock my odd socks!" was briefly scrawled on her entry).

For a short time recently, Dolly Parton's breasts were matter-of-factly described as "monster-sized". Hardly a week goes by without one of the more creative or subversive additions taking flight, adding greatly to the gaiety of the nation. Most recently, Alan Titchmarsh - not-very-proud recipient of the Bad Sex Award for embarrassing passages in fiction - was said by his Wikipedia page to be penning a new Kama Sutra.

Robbie Williams was once declared to have made his pre-Take That living "by eating domestic pets in pubs in and around Stoke". For about six weeks, a Wikipedia page was reporting that Margaret Thatcher was fictitious.

For celebrities, you know you've arrived when you have a Wikipedia page created about you. But you also know that you hit the very top only when you die in Wikiworld.

Miley Cyrus, Oprah Winfrey and Apple founder Steve Jobs have all been declared dead by hoaxers in the past year. All are still alive, most of them kicking. Barack Obama's inauguration day was the final straw for Jimmy Wales, Wikipedia's founder and visionary-in-chief, who declared that it was time to break with the tradition of "anything goes".

That was the day two senior senators, Ted Kennedy and Robert Byrd, sparked a flurry of concern about their health when they left the inauguration lunch on Capitol Hill - in Kennedy's case, in an ambulance after a seizure. Anyone who reached for Wikipedia for the latest facts found that someone had prematurely filled in 20 January 2009 as the date of their deaths.

Whether the editors were motivated by malice or whether they were taking what journalists might call "a flyer" in the hope of being first with the news, the incidents prompted another round of unforgiving headlines about Wikipedia's tendency to err. Wales is following the lead of the embattled TV bosses who agreed, after the revelation of Janet Jackson's nipple during the 2004 Superbowl, to put a time delay on the broadcast.

From now on, he proposes, editing the biography of a living person will be a two-stage process; anyone can still make a revision, but it will have to be flagged as "approved" by someone higher up the Wikipedian food-chain before it goes live on the site. "This sort of nonsense would have been 100 per cent prevented by flagged revisions," Wales thundered after the Kennedy-Byrd embarrassment, and he ordered a trial of the new restrictions.

But the very suggestion has stoked a monster of a controversy among the faithful, even by the standards of a group of obsessive-compulsives for whom controversy is a permanent state.

Wikipedia is, after all, the encyclopedia written by the people, for the people. Wikipedians are engaged in a constant fight to rid it not just of vandalism, but of all opinion and contentious material, of anything that cannot be described as fact and supported by a link to a recognised source.

To click "edit" to muck in on an entry, or "history" just to examine the palimpsest on which it has been created, is like lopping off the top of an anthill, revealing the extraordinary industry inside. It looks anarchic, but it is governed by a vast array of rules and conventions and manipulated by a hierarchy of editors and administrators, elected to their posts on the basis of their work. They wield significant power to delete revisions and whole articles, and to block users.

Every single change to every single article is recorded and can be debated. "Edit wars" between contributors who are pushing competing revisions are common. Many are tedious - the debate about whether J.K. Rowling is pronounced "rolling" or with an "ow" sound ran for months - but participants console themselves with the knowledge that they are working towards a more perfect union of Wikipedia and the world it describes.

The new plan for flagged revisions only extends a current policy that denies editing rights to anonymous users on the pages of major political figures - a policy introduced during the constant war against vandalism to the pages of Tony Blair and George W. Bush in the run-up to the Iraq war. Its detractors argue that a similar clampdown on the German language version of Wikipedia has meant it can now take three weeks to see an edit appear there.

In Germany, since last summer, all edits to all pages have had to go through flagging. "This will drive away newcomers, create a backlog of massive approval queues, cause an exodus of editors opposed to oversight by the WikiBureaucracy of their edits, cause umpteen edit conflicts, create a system of prior restraint, and place a chilling effect on the development of Wikipedia and the greater project," user Katana0182 wrote in response to Wales. "This is like assuming bad faith on a massive scale."

How big is the problem really? Reid Priedhorsky, who studies Wikipedia and similar social projects at the University of Minnesota, estimated in a recent paper that the chances of any one visitor seeing a damaged Wikipedia page are about one in 140, as the average time it takes to repair damage is less than three minutes, even less for heavily tracked pages.

However, there are still more than 100,000 damaged pages at any given time, vandalism appears to be on the increase and it is impossible fully to measure the scale of the problem. "It's the monster in the closet. You know that it has not grown bigger than the closet and busted down the door, but you don't know exactly how big it is in there," Priedhorsky said.

However, the most startling fact about Wikipedia remains how accurate it is, not how inaccurate. "As a researcher, I'm baffled that it works, but Wikipedia is one of the wonderful things that has happened in the 21st century. Many hands make light work. There are millions of people who edit Wikipedia, and many of them track changes to the pages they are interested in. I have 43 pages on my watchlist, for example, covering subjects I know things about. Any controversial edit is likely to be quickly seen by many people."

What opponents fear most from the new "flagged revisions" rule is that it could put off a new generation of writers and editors, slamming this extraordinary global phenomenon into reverse. It's not something that seems to worry Wales, a bookish, bearded guy who presents a Steve Jobs-style face to the world on behalf of the community he founded. He describes himself as "pathologically optimistic".

Wales recalls his wonderment as a child at the World Book that was his first encyclopedia, bought for him from the travelling salesman who showed up at the family home in Huntsville, Alabama, one of the scientific hubs of the US space programme. Born in 1966 to a private-school teacher and a grocery store manager, young "Jimbo" Wales excelled at maths and made a beeline for a lucrative career in finance where, as an options trader in Chicago, he made enough of a fortune to support himself for the rest of his life.

Sensing another pile to be made in California as the dotcom bubble inflated, he headed to Silicon Valley to start Bomis, a company that ran what he euphemistically describes as a "male interest site". This first venture in smut and soft porn was short-lived, though, as he hit on the idea of creating an online encyclopedia.

Typically, the facts are contentious, as a glance at the interminable history of the Wikipedia entry on Wikipedia will attest. Wales shares the credit with Larry Sanger, a website editor who also has an interest in philosophy - but he shares it reluctantly. The two have been involved in a long-running dispute over exactly who came up with the idea for creating a Wikipedia community. Wales sniffily highlights how Sanger was, in fact, only a hired help, employed by Bomis to work on a professional online encyclopedia called Nupedia, built on the traditional model of editing by experts.

Wikipedia was conceived as a way of quickly building Nupedia content - "wiki" is Hawaiian for quick. Sanger was firmly planted on the accuracy side of Wikipedia's accuracy vs access debate, and he has made it a mission to prove to the world that there is a better way. These days, he is the man behind Citizendium, a new Nupedia that's edited by a cadre of academics expert in their subjects, which he launched with fanfare and not a few digs at Wales. But it has failed to take off and has fewer than 10,000 articles almost two years after launch.

A more credible challenger is Google, whose own effort, Google Knol ("knol" means "a unit of knowledge", the company has decided), is still most useful at the moment as fodder for Silicon Valley jokes. The search engine giant professes itself satisfied with Knol's first six months, however, and it has grown to 100,000 articles in less time than Wikipedia managed.

In an effort to pull itself into contention, Citizendium is trying to muster its users into a "global write-a-thon" tomorrow, while Google Knol is offering a US$1000 ($1900) cash prize for the best new article written before March. Even with these efforts, it seems difficult to conceive of any of these other projects eclipsing Wikipedia in the popular imagination, unless the market leader goes into some sort of self-induced meltdown, which is why Wales remains a pivotal figure. As a kind of philosopher-in-chief, he continues to dominate the organisation, to steer its debates, to calm its collective neuroses. Wales is never anything less than a controversial figure. He has batted away allegations from former colleagues that he used Wikipedia as a personal piggy-bank, paying for $300 bottles of wine and trips to Russian massage parlours. He has faced controversy even over his age, with suggestions that he doctored his own Wikipedia entry to knock it down a couple of years (which is why his date of birth requires no fewer than four footnotes).

The battling over his own Wikipedia page reached fever-pitch last year as it was revealed that he had been conducting a relationship with a Canadian TV pundit, Rachel Marsden, who first contacted him to get her own Wikipedia entry changed. No sooner had he denied accusations of misusing his editing privileges than the relationship soured in spectacular fashion, with Wales announcing its end on the internet and Marsden putting some of his possessions up for sale on eBay.

Wales is a force of nature kind of guy, travelling the world extolling the virtues of the open-source nature of the Wikipedia project. But one fact, above all, assures his leadership status: he could have got very rich from turning Wikipedia into a traditional media company. And yet the once-ramshackle Wikimedia Foundation, the charity charged with guarding this great public resource, is edging towards a more professional structure under its ferocious executive director, a former Canadian journalist called Sue Gardner, in the role since 2007.

More than a few Silicon Valley gossips have begun to speculate about boardroom in-fighting and about Wales' relationship with the organisation, particularly since bloggers reported delays in having his board seat confirmed at the end of last year. At the very least, Gardner is trying to impose order on an extraordinary bureaucracy and to put the foundation on a firmer footing so that it doesn't require seat-of-the-pants fundraising efforts from Wales, who fronted an appeal to "keep Wikipedia free" in December that brought in US$6 million ($11.46 million). The aim is to keep Wikipedia free of adverts, even though the costs of its hunger for bandwidth are rising exponentially as the site continues to grow and the records of changes lengthen. The foundation's finances are the biggest single threat to Wikipedia, according to Reid Priedhorsky.

"A successful community artefact like Wikipedia requires strong buy-in from the community, which I'd wager is much harder to achieve under a for-profit model," he said. Instead of the nine-person staff crammed into an office in St Petersburg, Florida, which Gardner inherited in 2007, she now employs 23 people in the heart of Silicon Valley. They include lawyers, professional fundraisers and advisers keen to exploit Wikipedia's brand with lucrative new ventures such as real-life book publishing.

The latest development has been to appoint Roger McNamee, a veteran from the tech industry who currently runs the venture capital outfit Elevation Partners along with U2 front-man Bono, to bring more business savvy to the foundation's advisory board. And, while the Wikimedia Foundation has no formal role in deciding policies within the Wikipedia community, it is watching closely and with trepidation. At today's crossroads, the signposts marked "accuracy" and "access" lead down very different paths.

The near-death experiences of Ted Kennedy and Robert Byrd do more than confuse the public and distress their loved ones. They tarnish the Wikipedia brand. In monetary terms, "never wrong" is more valuable than "never wrong for long".

The economy of the Republic of the Congo is a mixture of village agriculture and handicrafts, an industrial sector based largely on petroleum extraction, support services, and a government characterised by budget problems and overstaffing. The Congo's growing petroleum sector is by far the country's major revenue earner. In the early 1980s, rapidly rising oil revenues enabled the government to finance large-scale development projects with GDP growth averaging 5 per cent annually, one of the highest rates in Africa.
