[Ineffable]

It would be a problem if you couldn't simply ignore or block anyone you didn't want to talk to. There's plenty of people I would have lost touch with years ago were it not for Facebook. When it's someone I want to talk to, I'm grateful. When it's not, I just unfriend them and my privacy options do the rest.

There is a bit of a problem in that many teenagers don't seem to understand the fact that it's very difficult to delete things from the internet. It's a non re-writable medium, in many respects - particularly if you're not smart with your privacy settings. There is definitely room for more education on this. It would be way more useful than the joke that was IT lessons at my school.
