OpenID is a great thing for the web. If you own an account anywhere on the net that can be used as an OpenID, you can instantly login to so many other services using one account, it is a promise for the web user.

Google has understood this. And now for the great news: Blogger supports OpenID logins. Isn't that cool? For instance, if you have always had a VOX account for blogging and such, you can now use that account to login to blogger too. But even better: Google's blogger login now also acts as OpenID, enabling you to login on any other OpenID accout on the web. Fabulous. The net is becoming a better place every day.

Google's Blogger is here: Blogger.
