Well, it can be a great social networking tool if people would use it properly. Instead, its just a bunch of idiots and teenage girls. While I do have a FB account, I hardly ever even use it anymore except for when I am drunk and wanna talk shit about some of the more inane posts I see.
Well that, and the extended family tend to organize get-togethers via FB so I use it for that too.
And GoGeTa, about the post topic; I can not say that I have seen any morbid FaceBook posts, but I do see plenty of them that make me want to kill myself.
I use FB mainly to check up on RL friends & family that I don't see a lot, and as a replacement for emailing the same. I have a small handful of people friended who I either met once or twice, or are people that I don't otherwise know well, e.g. friends of friends, people who remember me from high school 20+ years ago, etc.
I have a few rules about FB: I don't repost jack shit; I don't spout someone else's idiotic pop culture wisdom in picture form and then claim to identify with it; I don't get in arguments with the people who
do post idiotic pop culture wisdom there; and I block all the damn FB games. While it's occasionally amusing to see a meme here and there, I never post them. A few authors & bands I like post on FB every once in a while, so I find some mild interest there.
What I share there is mainly a blurb once in a while about whatever boring mundane thing is going on my life at the moment, so that people I don't talk to regularly will know I'm still alive.
