The Enron Explorer lets you search through the emails and social networks of Enron, circa 1999-2002. Even kottke.org made it in there. (thx, dylan)
The social networks of the rap music world "differ from all other human networks". By and large, successful rap artists don't collaborate/hang out with one another, as usually happens in other human social groups. (via cd)
Friendster has a new feature...you can tell who has looked at your profile (feature is on by default and you can turn it off...if you're even aware of it in the first place). If I still used Friendster (not that I ever really did), I'm not sure how I would feel about this. On the one hand, you can tell if someone's interested in you (that guy you just met at the bar found your page as soon as he got home), but on the other hand, you might not want the girl you have a crush on to know you're obsessively reloading her page to check for updates. (Also, imagine if they added this to LiveJournal...)
