Hei sure am glad to know that Technorati is number one on your list, I recently found out that my site was listed there too
I don’t know how it got there, possibly someone liked my post and “technoratized” it there?
One thing though, at the technorati site where my site was shown, it’s stated there No Authority. What does it mean??
I need to register my site with technorati or what??
Anyone knows?
Most probably your site is still new. Don’t worry.
