Blogger is experimenting with OpenID and is trying to make it easier for people who don't blog on Blogger to be able to comment. I just noticed that a non Blogger gardener tried to comment with the old feature and was having trouble. I've enabled the new comment feature through Blogger In Draft to see how it goes.
If you have a WordPress, LiveJournal, TypePad, AOL/AIM or any OpenID test out the comment feature and let me know how it works for you. You can read about the new comment options on New feature OpenID commenting.
I'm not a fan of this but if it makes it easier for us to cross-polinate our garden blogs I guess I can live with it.
I just tested the new feature and I left a comment with my wordpress ID and it created a link to the blog over there. Which btw, has no real content of any kind.
I'm not receiving notification of the comment I left with my wordpress ID so I'm going to disable openID comments on this blog until they fix whatever problems they're having with this. If you're unhappy with the new comments feature please visit the link above and make yourself heard in the comments section of the official blog.
to non Blogspot users
I just saw that some people are suggesting you leave your link in the comments section since you can't link back in your screen name. I strongly suggest that you don't do that on blogs where you haven't established a relationship. If the blog owner is anything like me you'll probably have your comment deleted because you'll be mistaken for a spammer.
One thing you could so is if you have a Gmail account is create a blogger profile. In your profile you can add a link to your website in the left hand side and in the "about" section you can link to your non Blogspot blogs. I use the about section to link to my most active blogs on Blogspot. For an example see my profile. I have a few Gmail invitations to give out if anyone needs one, you can find my e-mail in the profile link.
