Why should I use OpenID?
marrone: Well it is not too difficult to implement and it can speed up the registration flow for new users, which should always be a good thing.OpenID is still getting better though. Yahoo! just became an OpenID provider which should help it catch on. And the ClickPass guys have built a great tool on top of it as well. So it looks right now like OpenID will survive and become better in time and perhaps achieve the goal of replacing the registration flow.So while you say it is not the cure right now, I think that if you give it enough time it possibly could become one.
