I keep up with my family and have found friends there. I even have gotten work from it! I network with others in my business and related businesses.
I don't play the games. Oh- everyone comments on how I post how much stuff I do- canning, sewing, etc. (I have 2 friends that say they check what I put there all the time- they like the fact it's always positive.)
I have friends from the qb here as my friends- I like that I have a huge circle of friends with many interests.
Oh- I only "friend" people I know.
