Hmm …. well, I am on FB every day (I am right now, in fact) and have several Pixies on my friends list already - DB, PF, TXGrneyes and Osuche to name but four.

I have a Google+ account, but hardly ever use it, likewise with Twitter. Not tried tumblr yet.

Not sure if I qualify under your criteria though!!
