I like Facebook. I use it every day to actively and purposely promote my worldview–really. You can befriend me here if you like. (If you would like to de-friend me, you can do that here perhaps.) But the fact is, with all it’s benefits, Facebook is starting to go to far, and someday, something will likely likely replace it [and if you're a geek, I'll say parenthetically that I hope the new place is open-source--even though I didn't use parentheses].
There are lots of great things Facebook is doing behind the scenes. I really like the connections between companies, in fact. But Facebook is facing a brewing rebellion. Complicating things like this is one of their sick symptoms.
