This is my first post with an actual tactic so if this is something that is common sense and I'm an idiot, forgive me. But, I have been using a really simple way of getting Facebook friends incredibly fast. Just log in and join some of the more popular groups like Farmtown or Mafia Wars or something and post on the wall something to the tune of "Level 30 here will neighbor the next 15 people to add me" These more popular boards will turn over posts every 15 minutes so you can post like 4 times an hour without getting caught as spam or anything. The friends literally come flooding in by the 100's. It's a noobie method but...I'm a noobie.
