If this opens up to everyone, then you've just got another myspace which is pretty much useless. If you want to be myspace then just get a myspace account.
I chose to join facebook for many reasons, but mainly because it was safer than MySpace with it's particular audience. I will delete my profile if Facebook opens to the public.
Facebook should NOT ever become public. It's bad enough it's open to high school kids now. I like the college-oriented atmosphere of Facebook. It seperates Facebook from any other social network that any crackhead can join.
i signed up for facebook because of the small bit of privacy that it provided, even on the internet. opening facebook to everyone eliminates the bit of security i felt in signing up. please leave facebook the way it is.
