The only socialising I do is right here at Stardock.... on the forums. Outside that I'm simply not interested, having been burned by Facebook after just one visit and never wanting to go back. I have never been to Twitter or any of the others and never intend to.
I did open a Youtube page of my own once but rapidly lost interest in it and now I don't know if it's still there after being absent for more than a year. It just wasn't my thing.
