Why didn't you just remove friends and then keep using it? That's like saying you gave up on using email because of all the unanswered messages you had sitting in your inbox.
But I'm edgy and avante-garde and so I did disable my Facebook account for two days. Restored it almost instantly. It's not that there's an addiction, it's that Facebook is so easy to bend to your needs that outright deletion is stupid.
I removed all but ten friends and suddenly Facebook is a way of talking to friends and being vulnerable and the whole shebang. I've got no complaints. Literally none.
Plus there are other ways I keep in touch with my closer circle of friends: instant messaging.
The other benefit with that is that when I say something, it isn't pushed to everyone else. Even if I delete friends, conversations will still be open.
I don't understand why facebook can't just keep doing what made it popular. The fact that it was a closed network for only real people you knew, not random internet "friends". Why follow in the footsteps of twitter when you already have something useful. I stopped using facebook once my friends list grew into the hundreds, trying to open it up even more is probably going to result in less usage.
