Spock, the search engine that helps you find information online about specific people, has come out of private beta today.

Spock uses data from MySpace, LinkedIn and other sources to return infomation about the people you search for – giving details such as age, occupation, as well as some general background.

Users can then update profile information, adding links and tags to help users search for related people. You can also register and create/edit your own profile on the site.

The private beta has been popular, with 30,000 new signups per week, though the fact that the site is running slow right now may indicate teething problems.

Another people search engine, Pipl, launched earlier this year. At the moment, it seems that Spock has the edge, as the information from its searches is more relevant, and can be edited easily.
