I don't see why you should decide to never have a social account. Personally, I don't trust Facebook, so I don't use it. Twitter, on the other hand, I've found useful both to follow people I know or know of in the context of a hobby &c., and as a microblog for myself.
I have never, nor shall I ever, maintained an account on Facebook.
This means that I will forever opt out of commenting on TC articles.
