Technorati and Digg

I have recently signed up to both of these sites, for different reasons, but have been stunned when my chosen user name of length has been accepted on both sites. I would have thought that sites like this, with so many users, someone would have claimed that username long ago. My Technorati Profile and my Digg profile I haven’t used them much yet, and I am sure that my allegiance will fall one way or another, but I figure its about time I give it a go.
