Der Beste
I read some and say happy birthday to people if I notice that it's someones birthday etc. I don't post much myslf because it's enough that you people know what I'm doing, not whole FB (ok just my "friends")
But you can make groups of friends, limiting/accessing your profile. (depending on who you want to give access or not of course)
That's what I did.
And I did play games, but I don't anymore. They're boring.
