Technorati Claim
I've been asked by several clients to help them claim their blogs on Technorati. Clients don't want the obnoxious javascript on their site that Technorati tries to inject with their embedded claim and they really don't want to add a "Technorati Claim" link to a post on their enterprise system; it just looks cheap.
For these clients, I've started putting their claim in their top post on their site inside a hidden div. It seems to work nicely and you don't expose the link to your readers while still getting the benefits of the Technorati claim.
I've tried a hidden paragraph and hidden div and the paragraph didn't seem to work but I can't think of a reason why it wouldn't...
Here's how to do it - find your latest post in the control panel under my blogs->all posts. Edit that post and flip over to the HTML editor so you can paste HTML rather than rich text with encoded HTML characters. Add <div style='display:none'></div> to the bottom of your post then paste the <a href='http://technorati.com/claim/xxxxxxxxx" rel="me">Technorati Profile</a> inside the <div> tag and you should be good to go!
For those of you who are really cautious (like me), start a new post, add your hidden div and claim link then "Save, but don't Publish" and view the post to make sure you've got a hidden claim then go back and update the published post, wait for cache to update and claim your blog.
