Refacer Adam D. tipped us via our fan page about a new Facebook page that ranks your friends who brought the most people to Facebook. In addition to a top 10 (or 9 and then your position) of inviters, Facebook Impact also keeps track of the number of invites you’ve sent out, how many of them got accepted and by whom.

You’re probably a fan of at least a handful of brands and/or products on Facebook, and that’s because you’re truly fond of them.
