I like having FB, but mainly because I have learned to be selective about who to have as friends.
If any post is annoying, I use the Hide feature, just so that I don't have to see it.
If a friend posts every 2 hours or so, I might hide all posts from them for a while.
I love FB for humor. I much prefer pinterest, however.
Two things that annoy me on FB:
* The Close Friends feature - any of your friends can basically stalk all your activity.
* How so many seem to not understand or care about the globe/world/public icon.
When I see that, I very seldom hit "Like" or comment on their posts. It's important to remember that if you hit "Like" or comment on someone's world/globe/public icon, then your Like or Comment is public also.
The only thing that I allow on the world/public icon is my Cover Picture, simply because I have no choice. Everything else is set for "Friends Only".
