You know, guys, this topic wasn't made on the premise of what things people do on FaceBook that you hate, just things you or people you know do in general. Yeah, there's all kinds of stupid people on the network, but it'd be more cool to hear clever things people do rather than stupid things. Because, you know, that's more rare.
A few friends of mine used to post status messages about every single thing they were doing during the day, right down to when they're going to bed at night. So I started doing a "Like" on whenever those people said they were going to bed/sleep. I was hoping they'd start getting freaked out and ask about it, but no one has asked yet. Ho hum.
