More in the "People Love to Hear Themselves Talk" category: just saw a sponsored ad on FB for tree-free eco-friendly toilet paper. OK, fine.
That *sponsored ad* has almost 5,000 comments on it. ON AN AD. And, of course, being Facebook, the comments are mostly of the "this is so obviously stupid and bad and I can see it so what can't everyone just agree with me because I'm clearly right?" variety.
