[OpenID] The Various Methods For "user at domain.com" Style Identifiers

[David Nicol]

I am for an approach of leaving all systems as they are now and adding
a convention, provided by some openID identity service, that maps
e-mail addresses into openID urls, and then trying to popularize that
service, or the various services conforming to the to-be-proposed
convention,  so that when someone types joe at example.com into the
openID slot the identity widget offers joe a choice of
http://smtp.openid.tipjar.com/example.com/joe and a few other similar
services suggesting the rewritten versions.
