I think you missed an L in the title.
As far as social media goes, I quite enjoyed twitter a while ago. Facebook I never really liked, so that account was "deleted", or as deleted as you can be on facebook, a while ago.
Recently though, this, lainchan, steam and a few other sites are about as social as I get.
Thinking about it I'm not sure what you would classify as social media. Technically, even if anonymous, it's still social networking... kinda.
