MASHABLE - May 9 - YouShouldTotallyMeet is a new Facebook app that matches friends of your friends. You first build an app profile for a single friend that you want to set up.Through the app, you then write some reasons why someone should meet your friend. Mutual friends can even vouch for them with "agree" and "disagree" votes. Then, you go through your own friends list and find people they "should totally meet."
