Tom,

OAuth definitely sells itself as more than just a non-password-based
authorization protocol. Just as important as not sharing the user's
password is the value/usefullness of the information being accessed to
service consumers. Look at where OAuth 2.0 is headed with the
inclusion of scope parameters in the standard. Even the "hello world"
use case of OAuth is a user granting consent to a printing application
to access "their photos" on another website. As a user who setup my
own account on twitter I should be allowed to selectively share pieces
of MY user profile with other apps. Facebook obviously get this, and
while I am sure the folks at Twitter do too, they have chosen not to
provide this function. That is is an unnecessary inhibitor, not a
selling point of the site. I am not suggesting it should be in the
default scope, but it should be requestable via a scope parameter in
the redirect-for-authorization step, and if granted should be in the
returned data.

I have developed implementations of OpenID, OAuth and Infocard from
the ground up, so know precisely what the capabilities are. OpenID
doesn't offer any more or less in the way of attribute sharing than
OAuth - it's what the deployers of the technologies choose to expose
from their databases that makes the difference. I'm suggesting Twitter
should let users decide what to share, not always hide what many
consider to be the single most useful attribute of a user's profile.
