#3. Wink.com

With more than 200 million people signed up for social networks, how can you quickly find your best buddy from second grade, that guy you dated in high school, or your co-worker from three jobs ago? The people search engine Wink.com sorts through all of these profiles so you can easily find and connect online with long lost friends. Recent upgrades to the site also allow users to control their search profiles on the Wink search engine. Delete that unflattering picture, remove the rude post, and present yourself as you'd like to be seen — instead of letting the search engine take complete control.
