What crap, I joined Facebook because it was an asylum for us college students from the crap ridden Myspace and Friendster websites. Now it's becoming too corporate. Gay.
I wasn't a huge fan of Highschools being added, and have used it less since that change, and going public will make me not want to use facebook at all anymore.
If facebook information is open to everyone, it will be a larger security issue than the recent mini-feeds. It will degenerate the whole thing into Myspace, and no one wants that.
