As I told Jared and some of you, I am worried that we're entering a slippery slope where we start designing incentives and functionality around real names and we end up treating pseudonym users as second-class citizens. There are many intermediate options between real names and  "cheap" pseudonyms. Paul Resnick and Kaliya Hamlin gave excellent presentations at the Reputation workshop last year [1] on many alternatives that can be explored. I asked them to share a couple of readings on this issue and I'll forward them to the list when I hear back from them.
