[OpenID] [oauth] Re: Replacing email verification with RSS 'push' feeds and OAuth

Hi Allen,
Thanks.  Incidentally, the grief I have with Facebook is that I have to
visit Facebook in order to pick up my "mail" which may just be a poke or
prod.  *grumble*  But yes, I'd like to see us provide a general solution.
 And my personal queuing SP of choice would likely be one that sends copies
of my messages in the email it sends me, as well as organizes them within
its own web site for my review later.

And yes, certainly some sites definitely have more use cases for email that
this solution doesn't address, like the social networking sites, I agree.
Although I hope we can find a way besides giving these social networking
sites access to spam our friends to make these connections with others
already using the service.
