The UK's The Independent does away with anonymous commenting.
The New Yorker's famous cartoon "On the internet, no one knows you're a dog" is now challenged by Facebook's Mark Zuckerberg, who defends Facebook's dismissal of privacy concerns by declaring that it is now impossible for anyone to maintain several separate identities. You are who you are, and everyone's going to know it, is his implicit declaration. In otherwords, on the internet everyone knows you're a dog.
Zuckerberg has a point. Anyway, I'm with the Independent. I don't comment anonymously, and I'm not keen on anonymous comments.
