Andy Powell cites Cameron Neylon as posing a question many of us have asked over the years, "ow then is it that we have no way of citing a person? We need a single, unique way, of identifying researchers." But does it follow that we need a specialist OpenID service to provide unique researcher IDs? No. Researchers aren't somehow special - we need a system for identifying researchers, and any OpenID will do for that, not some some specially (self-)appointed registry of researchers.
