"I think that there are really obvious reasons this isn't currently happening. Tech-oriented, web-trained, fast-paced, hard-nosed Silicon Valley culture is not really that similar to game developer culture. Outside of GDC Austin... I haven't seen a lot of opportunities for the two industries to mix. Most crucially, everybody's too damn busy trying to get their jobs done to really spend a lot of time or thought on the issue." That gap in culture is something that still fascinates me.

"Locative social media is especially interesting because it directly affects how people move through the city. It can be terrifically fun and useful for people who fit its prescribed social model." This kind of proscription (or encouragement) of behaviour is interesting, and I think there are a variety of ways to do it "sensibly". And: how did you expand the group of "people who fit its prescribed social model"? Small changes of behaviour, amongst larger groups, are much, much more interesting.

Detailed write-up from Alice of a presentation from Turbine - the stuff on where to draw boundaries between game and web is really, really interesting.

"People think the interface is the game, and I think that is kind of backwards. I think the game is the game, and we should be thinking what are the many interfaces to it... you touch Twitter in many ways, you touch Facebook in many ways." Raph Koster. But you guessed that, right?

"There's a weird conceit in here, that the activities and practices of normal human beings will involve data processing and algorithms of some sort, which is an awfully big assumption. So big, in fact, that it has distilled down to a way of seeing the world as consisting of bits of data that can be processed into information that then will naturally yield some value to people... Design for people, practices and interaction rituals before the assumptions about computation, data structures and algorithms get bolted onto normal human interaction rituals."

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.

"I've never been satisfied with folks trying to build services that generate 'eyeballs' just to 'monetize' that traffic with ads." Charlie rightly lays into the monetizers.

Not every social software system has all of these, but most of them have three or more. And the most popular social websites implement many of these building blocks, but focus on just one or two.

Friendship helps people write community into being in social network sites. Through these imagined egocentric communities, participants are able to express who they are and locate themselves culturally.

"Most people are deeply invested in the physicality of life; this is not going away".

Surprisingly good (for .net) interview with Caterina Fake. “The most difficult part is not the technology but actually getting the people to behave well.”

"Privacy is not simply about the state of an inanimate object or set of bytes; it is about the sense of vulnerability that an individual experiences. When people feel exposed or invaded, there's a privacy issue." Loads in here that's of use beyond this qu

It is, after all, already social, writes Julian Bleecker. He's right. Ties into my ideas around 'sociable" software.
