Any good examples of "Social Sign In"? For the little web toys I make, I don't want to make full sign up forms, so I'm looking for any sites that are using Facebook / Twitter / Google / Yahoo / OpenID / etc for sign in. Something like what stack overflow is doing here: http://stackoverflow.com/users/login (only OpenID though).

I don't use blogger, but I post comments on a blog that does. I happen to run my own blog (impressed?), which I used to link through Blogger's "URL" field. Apparently Google has removed that field from the commenting form. Instead it goes to my "Blogger Profile" which of course is empty, and even if were full, it still couldn't link to my self-hosted blog. What is Google thinking? Anyhow, is OpenID my friend?

Is this possible? [more inside]
