So I tried out StackOverflow today and was met with something that suprised me. They only support OpenID.
I kind of like it. OpenID is a great concept and it'd be great if more people used it. This gives anyone wanting to sign up to that site incentive to use their OpenID, or if they don't have one, go get one.
That got me thinking. I'm working on a commercial website. I can't afford to turn away users because they're confused at what OpenID is, or if they don't want the hassle. But how could I make OpenID the preferred way of authenticating instead of the "alternate" way? I'm going to have to brainstorm on the kind of UI design that could help accomplish that goal.
