First speaker on the second main conference day was Marco Arment, who conceived of, then developed stand-out app Instapaper.

He talked about Apple and how the firm has 40 per cent of the smartphone market but a much higher percentage of the profits. One of his messages: "Don't build products for geeks; they're needy, disloyal, a tiny bit of the market - and they ask for weird stuff."

I did another count of Macs vs PCs. Today, there was a complete turnaround. Hardly a Mac in sight, but loads of little Netbooks and some Alienware speed-demon laptops.

Hah! Just kidding - from my vantage showing about three quarters of the entire space, I counted 40 devices on view: five iPads, five PCs. Thirty Mac laptops. Oh, 32 if you count the two on stage. Like one Tweet recounted: "Millions of dollars worth of Apple gear in this room." (With about 600 people in the room, there must be a lot more devices in bags. Maybe the PC users are hiding them?)

David McCandless from the UK is a well-known data visualisation guy. Seriously, geeks pass his visualisations around like other people pass around pictures of fluffy kittens.

I got a sick feeling when his animated visualisation showed how much the US spends on the military compared to the tiny budget the UN gets to sort out the world's problems - including those caused by the military.

Another fascinating one graphed fears as expressed in the press. A lot of his work includes clever data-mining hacks that target Yahoo, FaceBook etc. to dip in and collect key phrases in a tenth-of-a-second windows. The room lapped this up.

Fascinating examples of McCandless' work emerged one after the other: "Ready? Sure? Whatever the situation or secret moment, enjoy everything a lot" was the result of the data-mining of 22,000 horoscopes.

"This is my gift to you," he said. "Take this away and be happy."

He talked about the work involved (phenomenal) and how hard he worked to maintain integrity. Good stuff.

After the morning break, "Buttons are a Hack" Josh Clark came on.

I interviewed Josh yesterday and was keen to see his talk about the media, devices and the future of publishing.

He concentrated on what did and didn't work on iPad - he's an interesting bloke with a background in US Public Television working on documentaries, but then he moved into web development with the intention of exploring new ways of authoring content for dissemination. He has become a sought-after expert.

Jason Cohen was a coder who ended up running four businesses. Jason is the founder of Smart Bear Software and author of Best Kept Secrets of Peer Code Review. He talked about the complexities of business coming from the angle that all he knew how to do was code - what about all the other complexities of running an organisation? All the advice, however, is contradictory.

So his Lesson 1: You set the rules.

Got to say, his advice was terrific.

After lunch, 'hacktivist' Peter Sunde of the infamous and controversial Pirate Bay appeared. Pirate Bay was the largest file sharing system in the world. He's also the founder of Flattr, the first real social micropayment/money sharing service.

By the way, when I talked about the deaf language signers on the first day at Webstock, I wasn't being flippant. It was interesting to see how many people tweeted that they were using the service, and I know it's an exhausting and trying job. They did it very well, by all accounts. (I know a bit about Deaf Language. My grandparents were deaf and that's my brother doing the Fire Service ad on TV in deaf language.)

Sunde explained his background, starting out with computers as a 9-year-old with no money so he just 'copied' things. And later learned that this was 'piracy' and it was wrong. His story was extremely entertaining and funny. Pirate Bay became so popular, it has MPs in the European parliament.

The upshot of Flattr was that there's this huge information highway, and everyone is trying to make money out of it on one side, while on the other is this flood of free information and those who partake of it, and there's a schism between them.

The concept of Flattr (it's a combination of 'flat rate' and 'to flatter') to get revenue to the actual content creators. (It's probably the only way left to get money to WikiLeaks, by the way, after the institutions backed away.)

I suggest everyone takes a look at flattr.

I have interviewed the next speaker, Michael Lopp. You can read it here.

Lopp's an engineer who moved into management and spent eight years at Apple, finishing there in 2010. He reckons everyone will be - should be - doing something significantly different every three years. The fact that he can write (and talk) lent a great perspective to the proceedings, about both engineering and management. But for the products you build, he warns to remember the clients: "The thing is, there's a lot more human beings out there than engineers."

Lopp talked about the advantage a 'dictator' to a company brings as it represents a singular vision which means the crucial 'death to ambiguity', which drags enterprises down and wastes money and resources.

Since his whole talk, pretty much, was about Apple, once again I had that feeling - this would have gone down so badly here just a couple of years ago. But this audience was rapt.

I missed Tom Coates as I dashed back to the hotel to file my Josh Clark interview and got back for the second half of the very well-received graphic novelist Scott McCloud.

He's apparently holidaying here meeting other cartoonists, which is pretty cool.

Finally (almost), Merlin Mann came on.

He's an independent writer, speaker, and broadcaster based in San Francisco.

Merlin created 43 Folders, co-hosts You Look Nice Today and Back to Work and speaks and consults about things like email, time and attention, and creative work. But for Webstock, he did a rather heart-wrenching talk about fear, almost lost it when he mentioned his father's death and kinda wrapped it all together at the end with a positive message.

It was a bit difficult to figure out what to take from this, as the crowd of around 700 somewhat puzzled developers, designers and other 'net professionals were confronted with his rather raw discourse.

But crikey - I hope someone gave him a hug afterwards.

Then it was schmoozing with drinks while Amanda Palmer busked outside with her ukelele, then back into the hall for a Jason Webley performance (accordion and guitar), then Amanda Palmer (her keyboard is truly standout), then they played together and the evening finished, some worse for wear, others buzzing visibly.

If I heard any criticisms of Webstock it would be that there was a lack of consistency between deliveries and types of content delivered, but I actually think that's a strength. It led to everyone thinking, being challenged and examining their own motives and work. Which just can't happen enough.

I learnt something significant from every presentation, and from some, I learned many. Awesome.

There's only one ore thing to go - the Onyas Awards tonight (Saturday 19th), for which I hope to have the results online by midday tomorrow.
