Spock is a new sort of search engine that scrounges through information bases about people and tries to get you results that are a lot better than your average google/switchboard search.
I was invited to participate in the beta test, and have been allowed to invite others to participate. There is no obligation, although the thing does like to ask you to 'connect all your dots' by giving it your email addresses, "linked-in", myspace and other social sites.
Presumably by doing this user fed and automated "connecting", they'll eventually social network everyone and you'll be able to find people quickly and easily.
If anyone wants to play with it, PM me with an email address and i'll send you an invitation. Extra points for creative requests and offers of any form of bribery.
