She talks about preserving group #2 (pseudonyms) while agressively moderating group #3 (trolls). This is the most important balance to keep, and moderation is obviously a necessity. But I think there might be a way to inherently limit trolling by using the proper site design for social interaction. At Freeversation.com, we've developed an invite-only anonymous discussion forum where everyone knows who was invited to the conversation, but not who's saying what. In other words, an online form of Chatham House Rules.

So far, we haven't seen much trolling because we've eliminated the limitless audience of traditional anonymous forums. Our focused discussion groups are limited to relevant individuals only. I just think there has to be a way to promote honest, open dialogue without having to moderate each and every comment.
