Anyway, I never add people I don't know in person, although I do get a lot of friends' invitations from unknowns--I accept their invitations. People want to know you, why reject them? But I wouldn't add people I don't know because I already have a lot of people I don't know/care about. However, ATRL characters that are lovely like arkl, Lily GaGa, Rico and Niko, I added them. It's nice to have some ATRLers/Britney stans on Facebook. I mean, at least some people 'Like' your statuses when it's about Britney Spears.
I created a list called 'my buddies' on Facebook, and added my close friends (35 now) that I want to see their posts. And now instead of viewing useless posts by 340 people, I can check my besties' posts easily just by clicking on 'my buddies'. It helps a lot, I think y'all should do the same.
