Sometimes, but I usually have to have a purpose rather than just hang out.
As LinuxCanuck, BTW.

I spend more time microblogging on Twitter and Identi.ca as LinuxCanuck. I
am a news junkie do most of tweets and dents are informative and seldom are
personal. I am also on Facebook as the same, but have never taken a liking
to it. Too much of: want to be my friend? There is none of that on Twitter
and Identi.ca where anybody can follow or not as they like.

In all I have three identities on each of several social networks. Nothing
like having multiple personality social network disorder.
