Using the top-level blogs.bwerp.net for my blog and setting up additional blogs in subdirectories was a huge mistake, and one I regret regularly. Any sort of statistics or referral checking is completly inaccurate. Technorati is one glaring example, possibly in part to Matt's blog lacking a tilde in the URL. (Though I don't place any blame on his shoulders. I should have known better.)
It's far too late to fix the problem at this stage. There are hundreds of links back to every blog on the server, and changing anything would be a redirection nightmare.
This is something of a public apology, I guess. Dreadfully sorry for all this.
