Wink.com says they’re the largest people search engine in the world. But to me, they look like a people meta-search engine, pulling their information from the web at large as well as from MySpace, LinkedIn and other people search engines. Now they’re expanding their site to include profiles.
For once, the connection between a product (the people search website) and a social network actually made perfect sense to me: you can “claim” your profile in search results, then add to it or modify it.
The Wink Blog features a rundown of the key benefits of the new social network and I think they put the right one first.
