'"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.

"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."

My research is concerned with algorithms that exploit the combinatorial structure of networks and information.
