This reply still seems to indicate a fundamental misunderstanding of multifaceted identity. The fact that i am one physical person should be irrelevant to a reputation service. If I have one identity that I use to post jokes on reddit and another identity that I use to post serious content, those identities should have different reputations. What I do with one should not affect the other. My uniqueness should not have to be verified, the only thing that should matter towards my reputation is what the persona I am currently acting as has done before.

Yes. I totally agree. I would certainly love to support multiple distinct personas. There is an open question of how to do that while mitigating the damage potential. There are also cases where multiple personas might usefully be linked. For example, when commenting on programming issues you might want to link your persona to your stackoverflow identity or your HN account. Honestly, the biggest mistake I could make would be to assume I know what the community wants before we have a community. I think it's probably wise to err on the side of less friction and more prismatic identity and deal with restricting multiple signups if/when we need to. For now I plan to enforce uniqueness for outside identities (only one pseudonym per Twitter account) but also allow a basic reCAPTCHA username/password signup. If someone wants to contribute code to manage multiple personas within one account that would be fabulous, but annotation functionality feels more priority for me. If you think there's still a fundamental misunderstanding please continue, but I totally agree with your comment and don't think there's anything about it that's incompatible with my current vision.
