Fakebook is thankfully but a distant nightmarish waste of time memory as I had my account deleted last year. I definitely prefer mumsnet and you are all my new best friends lol (had to slip in a quick lol, just for the hell of it)
What I hate about Hatebook (sorry for any xposts):
All the sick inducing crap already described upthread - vile, fake! Most are from people who are in relationships where they scratch each others eyes out on a daily basis, then rush to post on FB just to validate their "wonderful blessed lives".
Cryptic status updates - attention-seeking. "Someone will wish they had never been born ". Look, Lovey, if someone pisses you off, either sort it out with them, or tell us what's the matter, quit with the drip-feeds, OK??
Pictures of dinner plates and glasses of wine (always accompanied with Nom, nom, nom) - thanks, I eat food too, and yes it is normally on a plate... AND???
All those bloody Fb Poker games, Farmville (do I care you just bought a pig - Crapinola-ville, more like) - that took up about 75% of my feeds, because I was Billy-no-Mates, after defriending most people for getting right up my nose!
Schmulzy stuff about God wants me for a sunbeam, meaningful inspirational sunsets etc, yards and yards of the bloody stuff clogging up the screen.
The only thing I can boast about was that none of the people in my Friends list were ever crass enough to take a photo of poor unsuspecting people with, shall we say, weight problems and mocking them on Fb (did you see that awful AIBU?)
That's just scratching the surface, but OP, YADDDNBU!
