I wonder about using something like Facebook Connect for commenter accounts, and using the person's full name that Facebook provides. People might be less likely to post useless or trolling comments if their real name (indexable by search engines) and even a link to their Facebook profile were attached to their comment.

They might be less likely to post lots of other stuff too, though. Do you really want any potential future casual acquaintance, boss, or what have you, to have instant, easy access to a transcript of every conversation you've had?

This would also rule out people like myself, for better or for worse, who refuse to use Facebook.
