I'm speaking mostly about FB but twitter has a touch of it to.
Ex: "here's what I'm having for breakfast"
"I'm constipated

"
"I'm at the mall"
"I'm bored"
"I'm ordering pizza"
"Goodnite everyone"
"GM FB"
"Lol"
Wait, you don't have friends you care about?
Honesty, social media brings us closer together with people that would otherwise be out of sight out of mind.
I can post a status about how I'm constipated and one of my medically educated buddies in the know can see that and give me a few tips and tricks on getting over it in the comments section.
If you're having a bad day, mention it and watch your friends give you positive messages and phone calls.
Hell, if you need a job and have a good social network you can get an offer in less than a week by simply asking for one in a status update or two.
I swear, are telling on themselves in this thread. Revealing themselves as the hatefilled basement dwelling nerdlinger losers that they desperately pretend not to be when hiding behind a screen name.
