I’ve just left a comment at the official blog for Blogger in draft. I did so using OpenID. For reasons why it’s good that we can do that, just follow the link.
In OpenID parlance, Blogger is now a consumer of OpenIDs. To be more specific, Blogger proper will be a consumer once the “comment using OpenID” feature moves there from Blogger in Draft (beta).
WordPress.com has been a producer of OpenIDs since March, but has not (yet) become a consumer. I hope that this move from Blogger reminds WordPress.com about OpenID…
