I've been thinking about this issue since reading Fall; or, Dodge in Hell by Neal Stephenson. It uses the concept of a Purdah: A pseudo-anonymous online identity. It's related to concepts of trust, fingerprinting, etc. It inspired me to built a WIP website where you create an identity by linking accounts in various locations, that the site proves you own. The idea is, you build trust / an identity through content you've written on a site - then someone who reads your post on another site knows something about your trustworthiness. I think an especially potent use is in reducing the change a given user (poster, reviewer) etc isn't a bot or marketer. We'll need to think about this more in the near future as internet communities (and public opinions) are more heavily influenced by bots and other forms of manipulation.
