Spokeo.com

Well, I heard about it on The Consumerist (http://www.consumerist.com) So I decided to try it. First, I discovered, its too easy to send a mass email to everyone on your contact list inviting them to Spokeo. (Sorry to everyone who got that...) But you enter someones email, and it checks for membership to any social networking sites. Basically an aggregator. Have fun with it at http://www.spokeo.com
