LiveJournal, WordPress, TypePad and any other blog host using OpenID can now post a comment to this blog and include their URL.
When you make a comment, look for this dropdown box:
Select your blog host, enter your user ID and password and you should be good to go. I guess this was to prevent someone from impersonating someone else. This is all in an experimental version of Blogger called Blogger In Draft. I found something in Blogger's help, which you can find here, but I'll go ahead and paste:
Blogger has removed the URL field for unauthenticated comments. Instead, we're rolling out support for OpenID, a technology for "signing" your comments with your own URL. OpenID lets you comment with the URL you want, while preventing others from impersonating you. Blog admins can turn on OpenID now on Blogger in Draft. Learn more.Why they turned off the unauthenticated URL before rolling out OpenID is anyone's guess. I BELIEVE that I've turned on this feature for this blog. I'm about to test it as soon as I put up this post.
In the meantime, I had a lot of fun playing with WordPress. It has a lot of great features that I truly envy in Blogger. However, for now I'm going to stay put.
