"I love Snitch.name.
Snitch.name searches information about your friends, mates, new collegues in various important places online, such as social sites and directories. You can also see how the name ranks on the social web.
Snitch.name? Why not just use Google? There are several advantages over a plain Google search! Some of them are:
1. There are several social sites that are not indexed by Google at all or in a very limited way. As has Tim O'Reilly agreed on: 'Social sites like Facebook/Flickr grow exponentially without being indexed by Google'.
2. Depending on your privileges to the various social sites, you’ll always get the maximum information that you are allowed to get. For example if you are in someone’s network in Facebook you’ll get more information in snitch.name than you would get directly from a Google search.
3. Google will not necessarily give higher ranking to results that are “people profiles”, so you get a whole bunch of results from mailing lists, forums, etc. that might have little value to you.
4. With snitch.name you get all the results expanded in your page so you can print them all at once and have them available when you are away from your computer."
