You know, I've never understood the mentality of people who complain about things that they've gone out of their way to be put out by. Like, people who'll see a forum thread's title, read through several pages of the thread knowing it's about something they don't like, and then post an entry complaining about how boring it is. What, did we force you to read it?
You don't like Facebook, fine. I'm not a huge fan myself. However, some people disagree with you and enjoy using it. Where's the harm? Shall we ban all the movies you don't like, burn all the books you're not interested in?
What's more a waste of time; spending time on a 'pointless' website, or taking time out of your day to complain that other people are doing it?
