Besides that though, I think it just encourages behaviors I don't really enjoy seeing in my friends. I definitely know people who in real-life are totally cool, but their social media presence makes me question why I ever liked them in the first place. Mostly I see a lot of:
1) very overt attention seeking for pretty lame things (like, pretty girls posting selfies of themselves doing nothing interesting, or dudes with gym photos, that kind of thing) 2) Extremely broad and poorly thought out political rants 3) sharing really vapid motivational quotes 4) people being maybe a little too vulnerable to a very broad audience, to the point where it's awkward. 5) This one is the worst of all. People taking passive aggressive swipes at individuals by posting very vague status updates. I hate stuff like that.
I don't think of myself as a super judgmental person, but whenever I get on facebook I spend half my time just thinking "really?" and then feeling kind of gross.
