I'm in my early 20s and I'm in the same boat. Reddit/HN/Slashdot are the extent of my use of social media and a lot of my peers in college were the same. Hell, I know a handful of people who work at Facebook/Twitter/etc who didn't even have Facebook/Twitter/etc accounts when they were hired, some of them still don't.

I suspect that an FB account for Facebook is "Mandatory" (because a lot of work is done "inside" FB - think of it as their internal comm tool, but of course you don't need to use it to post pictures of your weekend)
