Blogger and OpenID commenting
January 2nd, 2008 - Fred StutzmanWe’ve recieved a number of questions about this, so I thought it might be useful to post it to the blog. If you’re attempting to post a comment using an OpenID to a Blogger blog, you must prepend the http:// before your OpenID. For example, the following won’t work
But with the prepended http://, it will work:
Hope this helps!

That implementation is violating the OpenID specs. From OpenID Authentication 2.0 http://openid.net/specs/openid-authentication-2_0.html
=====
7.2. Normalization
The end user’s input MUST be normalized into an Identifier, as follows:
1. [detect "xri://" URL]
2. [detect XRI symbol]
3. Otherwise, the input SHOULD be treated as an http URL; if it does not include a “http” or “https” scheme, the Identifier MUST be prefixed with the string “http://”. If the URL contains a fragment part, it MUST be stripped off together with the fragment delimiter character “#”. See Section 11.5.2 (HTTP and HTTPS URL Identifiers) for more information.
4. [follow redirects and store the normalized result]
=====
In other words, the consumer (Blogger) MUST prepend the “http://” if the user doesn’t provide a scheme in the OpenID.
