OpenID is a useful thing and in fact it is like "the definition in terms of itself", because today you may avoid programming something to collect user's registration data and use OpenID instead.
OpenIDs are brillian for comments. Although it is slightly slower to follow several redirects and pressing additional button (to confirm that you allow provider to identify you).
But my question is: is there any OpenID provider related to Perl community? I mean that people who use Perl websites are often use the same nicknames which are not always equal to those used in livejounral or somewhere else.
I'd like to have an OpenID provider on use perl jounal, or even at openid.perl.org.
