Not on Facebook.
Do not own a cell phone.
Do not use Twitter, so I have never ....ted.
A few people have actually come right out and said I am a sociopath
because they perceive all that as being EXTREMELY antisocial.
I'm with you on all
three counts.
As for being a sociopath, tell them the correct term is
refusenik. I take pride in being one, particularly when it comes to cell phones. I've never owned one, which comes as a big surprise to people who have known me a long time, and recognize me as a gadget freak (which I am).

I relish times when I am incommunicado.
I have wifi in my car, multiple computers (desktop and portable), MagicJack, have been into shortwave, worked in radio and am in print media, strong supporter of Free Speech. Communication is great! On my terms. I feel no great need to tell someone I'm in the checkout line and will be home in five minutes. And, I've been dayum near run off the road more than once by an airhead who should've been driving, but wasn't. Facebook? Pfffittt.
