'"We studied these online gangs at the same time I was looking at the offline gangs and it turned out the model we were developing to explain the behaviour of the online guilds began to coincide with the offline gangs," says Johnson. "We could explain the data using the same mathematical ideas."' Which all makes sense, you know, but it's still interesting to see this stuff being done and taken seriously.

"I think issues of power and governance are going to swiftly rise in importance on internet communities, as they expand to include more different kinds of people. It's interesting that some of the best, most resonant ideas on these topics that I've encountered over the years has come from political writers and may have been produced even before the internet." Mike has read lots of books, and his quotations/sources here are great.

Some great notes from Dan Heaf on Clay Shirky's talk a week or two ago; I particularly like the notions of building not-quite end-to-end functionality, forcing the user to do something for themselves.

"Take the hassle out of organising football". It's been done before, but perhaps the brand, mobile experience, and quality of product will win out for Nike's team-management app. They showed us the MMO with Nike+; now they're doing guild management for the masses.

Awesome. Server set up to play karaoke; players mix appalling singing with a bit of the old ultraviolence. I miss PC gamers.

Absolutely excellent. A little depressed but also pleased at the overlap with my NLGD talk. Here's hoping I can munge together something good. And give credit where credit is due.

"...the same topic kept coming up, over and over... you can think of it as an amalgamation of crowd theory, human terrain mapping, and social simulation. It is the science of groups; it is a new kind of quantitative political science."

Awesome little greasemonkey script that overrides default send-to-group behaviour, and replaces it with send-to-multiple-groups-at-once.

A perceptive and detailed analysis of the Dunbar Number - and why some of the hype around it is misguided.
