OpenID: Enabled, not Required
I've been talking about OpenID, and hoping that it catches on so that everyone can use just one login credential to all the sites that are OpenID-enabled. It may or may not affect the user-experience. I guess it depends on how efficient servers communicate with each other. Kyle Neath points out 5 reasons why he would not be implementing OpenID. From what I've read, I think he simply disagrees with sites requiring an OpenID, not the ones that are OpenID-enabled. Having OpenID as another option to authenticate yourself is good, but using OpenID ONLY to authenticate yourself is not good. And he raises valid points.
