WordPress recently announced that they now support OpenID… to me this is a bit tricky. This is a portion of the post on the wordpress news:
Are you fed up with having to remember dozens of usernames and password? Does the idea of creating yet another account on yet another site leave you cold?
Yes, I am fed up. Why do I think they are not helping? While they allow you to use your blog as an OpenID, they do not support signing in to WordPress with a non WordPress.com OpenID account. Imagine every service (any service) provider did that. Blogger, MySpace, Digg, and so on. You would still have 3000 OpenID accounts because none of them would allow you to sign in with the OpenID provider of your choice.
Discussion can come around this: Should the OpenID providers be OpenID providers only? What does “supports OpenID” really mean (to me WordPress is just creating hype)? And so on…
I’m not using this *new service* I already have a different OpenID provider, and they DO NOT support the use of that.
