Sounds like the problem is not facebook, more like the friends you've added.
Personally living in Greece and having family back in the UK and friends around the world i find facebook really useful.
But then i only add family or really close friends, that way it's people i care about so IF they posted mundane stuff it'd make me feel a bit closer to them.
My Niece back in the UK visited the Harry Potter exhibition in London today and had Strawberries and melon for tea when she got back home.
Mundane maybe, still felt a little closer to her knowing that though.
In theory i could add a email group and email pics etc, but in practice folks don't tend to do that, plus it bungs up my email account, plus it's kinda nice interacting everyone over say a posted pic.
I think if folks use it like school kids by adding as many friends as they can, it tends to be a bit of a cry out for attention.
If you only add close friends and loved ones then why wouldn't you care about EVERYTHING they do?
Had many friends from work try to add me as a friend, but i simply explained i use it for family and close friend use only.
And they all think I'm mad for being on a forum like this, going swinging in the woods occasionally with blokes I don't know. It takes all sorts eh
