Why I Hate Social Media Sites

I've come to the conclusion that I really ought to delete my facebook profile. Here's the thing, it turns out I have no social skills. Apparently I am without a filter. Facebook actually causes me to hate people I normally would have liked. It's too revealing. People are self indulgent, hypocritical, judgmental (yes that one is me), and to be perfectly frank - unbelievably irritating. And I can't keep my mouth shut about it (obviously).
You see someone posting insanely personal information and you have to wonder, who is this for? For instance, a girl I had as a friend on facebook recently posted three messages in one day to her dead grandma. I knew this girl in high school. I barely know her now, and yet I'm looking at this deeply personal message to a deceased loved one and I found myself thinking, are you on crack? Why on Earth would you think this is a suitable medium for those thoughts? Don't you have any close friends you can call? A counselor you could talk to? Hell, even a journal would suffice. Why are you putting that up on facebook?
There are many other seriously annoying habits people have with facebook which I won't get into at this time. I've made enough enemies this week alone by being honest and blunt about my feelings on the matter. All I can say is, facebook seems to cheapen relationships. If it isn't important enough to pick up the phone and call me about, it probably isn't worth posting. I guess I'm just old fashioned, I prefer real conversation. The only posts I actually enjoy are the ones that make me laugh. If it doesn't serve a purpose, don't put it up. If we all asked ourselves 'who is this for?' before we posted anything, there'd be a lot less random shit I'd have to scroll through. And remember people, be a good friend - don't put up a chain post.
