I use FB a fair bit, can't say I've had particularly bad experiences except discovering that some of my friends are borderline UKIP members, which was very disappointing.
Twitter I don't worry about, although i do have an account created years ago because someone at work said it was important to be on it in the line of work I was in.
I looked for a few days and couldn't see any value in it, I still can't.
