Facebook...if you go too far.
See, as long as you don't take facebook too seriously, then it's a good time waster for a few minutes. Also like someone mentioned, it's a great way to catch up with distant (physically) relatives for free.

However, once you start to go on facebook daily, develop the Pokemon "Gotta catch 'em all" attitude to collecting "friends", keep telling everyone what you had for breakfast, lunch and tea, or you think you're such a cunting celebrity that all you have to do is post an emoticon as your status update and have the same bunch of people swarm to ask why you're happy today, then you're well and truly a facebook whore.

Don't do facebook
I'm on youtube though and get the odd message "I have added you as a friend, please add me to your friends list" from total strangers just because they've watched the same video as me. Wtf is that about?

Edit: I've even got people subscribed to my "channel" yet I've never posted a video.

Weirdos the lot of them.

I think you may have confused facebook with Twitter.

Tell me about it
I was recently angrily accused, by text, of intruding on someone's grief by posting a FB 'RIP' page for a friend's dog which had recently died.

Like, omgwtf innit? am i suddenly like 14 or sumfin?

The accuser doesn't use FB and neither does the late pet's owner. Someone had noticed a photo of the dog in question, among the hundreds of tedious cat/dog snaps on my account and told someone, who told someone else...

What I think it shows is that, disturbingly, there are people who don't use FB but who believe that everyone who does use it tells their whole life story on it.

Facebook has given me grief
Not directly but because of some people who've seen something and told someone, who told someone and I get a rollocking for posting something fairly innocuous. Mind you, I've started to ignore what these muppets say, so it's all good!! :o)

Yes
I know a girl who is exactly like this. Several hundred friends, updates her status (by iPhone) every time she farts, all her daft pals swoop on her status updates like it's a golden nugget of wisdom.

Why I have her as a friend I'm not too sure.

Oh yes, wait a minute, she's immensely tidy and has magnificent jugs. :-/

^^ This, in abundance
With one caveat, though: posting mini-status updates can be cute and a way of circumventing bans on MSN in the workplace, etc. I do however draw the line at Farmville/the app where you have to send your friends 'cool points' to transform into a different kiwi/other, because they're a total waste of time.

Friends who send me invitations for MafiaWars, Happy Aquarium, Kiwi Cool and so on: fuck off.

There is a facebook group, of which I'm a member
called something like "I don't care about your farm, your aquarium, or your mafia". I just hide all updates from those apps. Self indulgent tosspots.
