As I understand it, there's nothing to stop you using a separate Persona ID for each site you visit, and none of your IDs has to be tied to your real life identity. But most people already give the same username and same e-mail on loads of different websites, so we're happy to carry on doing that.

For now, most Persona users are stored in a central location by Mozilla. The idea is that e-mail providers take over authenticating users, so eventually there should only be a few users that Mozilla stores credentials for. I'm hoping that GMail will add support soon.

Hmm, I can see how this would be better than using facebook connect for the risk adverse (though I must question that if one is using something like facebook connect or google whatever in the first place).

But most web users aren't risk adverse, and I question the utility this will have over facebook connect when using it in some kind of application that the user wants to use that requires some kind of social data in order to get the most out of the app.

Great point. You can log into each website with a different email address.

Someone can build a Persona identity provider to automate Pseudo Anonymity.
