Have you claimed your blog at Technorati? It's a simple procedure, and it's a good idea to do it, if you want back links to your blog.
You need to create a free account on Technorati, and then choose Start a blog claim at the bottom of the page. Fill in all the details, and when you're done, you'll receive a code like this one: FTJ7VGWAJWEN
Create a new blog post with this code, like I do here, and then confirm it in your account. See illustration below.
Have you had any results, more traffic etc., directly from Technorati? Tell me about it in the comments.
