Facebook Reunited
Anyone remember Friends Reunited? Yeah, I bet you signed up once and never went back too. Well, it's had an ajaxy facelift, it's now free to send people messages and such, has pages for photos and video, and.. is a bit Facebooky. (In that you can now add family, friends, aquaintences, not just people you went to school with).
Looks good, but I think it's too little, too late. However, as long as they don't start letting you put zombies on the page, it's still a good alternative to the US-centric Facebook. Even if 80% of the people you know are on FB, and about 5% on FR.
