I can't speak for everyone, but I dislike Facebook for everything it's worth. When I had a Facebook, all I did was update my status with pointless crap. I mean, seriously, how interesting is "today I sat down all day and watched TV"? I don't have any friends in real life to communicate with online, nor do I want any. Instead, most of my Facebook "friends" were annoying family members that I can't stand; whom I obviously didn't get along with, while others were old friends from years past who're all doing better than I am (financially, etc.). Day in and day out I'd watch as others updated their statuses with a copypasta of some quote by some wise old man, and then everyone would comment and "Like" everything they said with some stupid crap, like "omg so true that's so deep," as if the poster had thought of it themselves. Many others would just talk about some random TV show, like The Jersey Shore, break ups with their boyfriends, or some other bs. In a nutshell, I generally use the internet as an escape. This means that it's the only place I can go to avoid annoying family members and idiots that I encounter on a daily basis (in real life). I didn't like its features, I didn't like the games, I didn't like its security features, I didn't enjoy my experience there. ...nor did Facebook provide any real usage to me.
As I've stated previously, I can't speak for everyone, but I can say for certain that Facebook isn't for everyone and everyone doesn't need a Facebook. In fact, it could make your life worse.
