This is probably old news but the openid blog claim in technorati is definitely a very good idea. If your blog is also your openid, when doing the blog claim in technorati you are given the chance to do the claim using openid.

With this option you just have to authenticate in your openid provider and ... it's done!

Just by having these two lines in my blog header allowed technorati to give me an easy authentication process.

<link rel="openid.server" href="http://www.myopenid.com/server">
<link rel="openid.delegate" href="http://pedrolima.myopenid.com/">

I was happily surprised with this process. Simple and easy.
