Having been reading about Small World Phenomenon (which I've been calling Small World Syndrome for some time now, guess I'll have to change) the other day I was vaguely interested in LOST when I was pointed at it. It doesn't really help model the interconnectedness of the matrix as it's a tree structure AFAICT, but I think it's an fun idea with about as much point as most social networking sites and none of the claims to usefulness. :)
I'd heard of Milgram before; my Mum did some stuff around Milgram's Experiment. SWP seems quite a different topic to me - are there similarities I'm missing or is it just the social psychologist equivalent of hacking on kernel code one day and a web app the next?
