I also deny any unnecessary applications, since they are largely a waste of time. Once you trim the fat of all the useless stuff, then it's actually a helpful tool, but only if the other people you know [and like] use it too.
It's also good for organising events, again because texting the address to everyone can get costly, and this takes away that unnecessary pain.
I figure it's easy to get annoyed at facebook/myspace but you can avoid the unnecessary crap pretty easily...
My thoughts exactly.
Facebook is a very useful tool if, like Dean said, you trim all the fat off of it.
I still get the occasional invite for one of their stupid apps, but it doesn't happen as often as it used to.
It got to a point where I would get 10-20 a day! It finally stopped when I posted a big bulletin telling all of my friends to not send me anymore invites. Not only do I ignore the invites, I completely block the app so no one can ever invite me again.
I primarily use Facebook to keep in touch with my old classmates from high school.
It can be amusing to talk to them on it and see how they've changed over the years.
