A friend mentioned Friendster to me the other week. I remember something similar being developed called sixdegrees.com (which I remember “wining” a t-shirt on many, many years ago), but that is now a travel/dating site.
Anyway, I've been looking more at the site, and filling in more details. It's interesting to see how people are getting linked and the personal networks are developed. If you are on there and reading my LJ, then shoot me an email, so I can add you 🙂
