It never appealed to me and always felt like a bandwagon and people then felt that they MUST open an account, for that reason i rebelled against it, its sort of like Glee and crime shows. They are hugely popular but I think they are very mediocre. I prefer MSN as a form of online communication as its just private and Facebook ..well there are issues with using information for advertising etc. that i just don't like and other things like site scrapers spamming your information that i read about.
I also think that the website is for people who are not self conscious about sharing their personal information.
Then you have this issue of people who you've met for five minutes finding out your name so next time you login to email you have all these friend requests from people you barely know, now what happens if you don't add them? They know you are rejecting them if you don't add them, that's how they see it, so what then?
Nup, way too much trouble for what its worth.
I don't really care about the people who use it to brag about the parties they go to, I did enjoy it when people would make a joke or would reference a funny quote or post a video, i do enjoy that but it got old. I found it too invasive.
You can't stay anonymous to people who you add if you involve yourself with facebook. People can ask you anything at the drop of a hat and there is no get out clause because they know you'll have read a message or your wall.
I can understand how some enjoy it though. I can see how it might have been fun for me back in 2004 when i was studying and we had a group of people working together, it would have been fun because the interaction of us in class would have coincided with facebook communication as well. But that was only temporary until the course finished. It's not like that all the time unless you have a big group of friends.
