I don't use Facebook, but I always see my coworkers glued to it. Their pages are filled to the brim with that kind of shit, and they regularly "quit" Facebook several times week because of it. What little I've seen agitates me to no end because it's usually just people echoing some shit they heard somewhere or posting some dreadfully unfunny attempt at a meme. Bumper sticker politics at its worst. So I'm guessing this is pretty common, and it's a pretty good reason for me to continue not using Facebook.
