An About-Face on Facebook?

I just read this article by Greg R. Notess, and I am also undecided about whether or not Facebook has done an about-face and is worthy of more educational or professional uses. As far as education is concerned, it would be intriguing to create groups for a class or use Facebook to search for people with similar interests or people who are associated with something about which you want to learn more. I feel like Facebook pages are more professional and organized than MySpace pages, and they are fairly easy to learn. But I also feel that it would be hard to get parents and administrators on board for using Facebook in the classroom. It is also hard to trust everyone on Facebook to be genuine and on it for the right reasons. However, I also think that because Facebook has been opened up to everyone now, it has the potential for everyone to think a little smarter about what they share and don't on their own pages. If I was in high school and had my parents as friends, I would make sure there would be nothing to get me in trouble on my page! As an adult, I have colleagues as friends on Facebook, and I make sure that everything on my page represents me well because of that.
