Have you seen Spock? It's a people search engine - still in Beta form but has heaps of people on it already. It pulls up information from existing social networks to compile information about people. It's like a Wikipedia - you can search for yourself and claim your entry if it's there and then add to it. So it means you can actually link all your sites, blogs, social network pages and so on. I thought it was just another network at first and ignored it last year - there are so many of them and I just didn't want to keep inviting people to join this one and then that one and so on - who's got the time to keep doing that? But this is quite different.
The info on me was pulled from MySpace and others have added to it - I just had to go in and say 'yes' that is mine.
