What other social networks do you use?

None. I just use Blurtit. I tried other sites but wasn't too impressed, one is just a sounding board for one user's political rantings, another is all but abandoned and a third is somewhere to go when you want to use foul language or talk about nothing but sex.

I don't use Facebook, etc either. People seem to post too much personal info on those sites.

I don't use any other social networks. This is the only Q&A site I use now. I belong to a few others but have not been on them for some time. I've never joined nor was I interested in joining Facebook.

When Blurtit was circling the drain, I started looking around; and I joined 3 or 4,

Blurtit is my primary site and the first I sign into during the day.

I still go to answer mug every day---there are a few wackos there whose answers I feel a strong obligation to challenge.

Just blurtit for me to.

I use Facebook and Blurtit. I do have accounts at www.ihavesolved.com and www.answermug.com but am seldom on them now that we have active moderation on this site.
