I use Facebook to keep up with local community events and business specials. All of my Facebook likes are local to me -- I have visited every one of them in person (or at least met face to face the people that run them). I don't have any friends.
I take that back -- I had three people find me through mutual "likes" and I accepted them, but I don't post anything. I also have not filled in any information about myself beyond name, email, and cell phone number.
