You know. That letter made me dislike Facebook a little bit less. I'm still averse to having an account on it, but those reasons aren't AntiFacebook, they're anti-people that might abuse Facebook, but I don't see FB as such a bad thing anymore.
[edit: Addendum: That said, you have posted that same link 3 times... once is enough, there are other things to say here]
I don't think Wall St. is used to companies like this.
