Just in case you need one...
No, this does not mean that this blog is going that way. But a lot of blogs are, so this may be useful.

I will mirror this post on the Science Blogging Conference homepage. Let me know if I missed you (i.e., if you ever mentioned or intend to mention the conference on your blog). This will be updated until everyone is exhausted!

You can follow the conversation about the Conference by checking in, every now and then, the Blog and Media Coverage page on the wiki.
I made one when Pharyngula went OpenID-only Creating the OpenID was cake. Getting logged into it and having that authentication carry over, however, wasn't. It's not intuitive for the end users. Plus for the blogger's side, it means you're depending on a third party for your authentication.
That said, I can understand the need for a unified identity across all sites -- having to log into Blogger, or type in my identity on your blog (without any sort of authentication, inviting spoofers), or depend on saved credentials on other sites, is a real pain. I just don't think OpenID is a particularly polished implementation. (Yet?)
Not really on topic: In other fields it is also often difficult to identify somebody. Therefore ISI introduced researcherID (http://www.researcherid.com/).
It will be helpful for all those Smith scientists.
Regarding ResearcherID, the Thomson Reuters developers have expressed intent to use OpenID when there is significant cause. The OpenID Society is attempting to build a bridge, using OpenID, between professional societies and publishers to help credential people and their scholarly works. By using OpenID researchers and authors can use their professional societies to extend themselves with much greater ease.
