I just noticed the list of blogoscoped's top sources.
   http://blogoscoped.com/credits/

Are "Metafilter" and "MetaFilter" supposed to be different listings?

One entry (currently #13 having 26 references) is blank.
Is this everything else?

The sources are currently linked via an "I'm Feeling Lucky" search.
I sometimes use this technique. It produces self healing links.
Some of these links do not go to the source.
Below are some examples.

"A" goes to wikipedia.
   http://en.wikipedia.org/wiki/A

Waxy at Feeeds goes to the blogoscoped archive.
   http://www.google.com/search?q=Waxy+at+Feeeds&btnI

Doing a blogoscoped site search might be another reasonable type of link either in addition or in place of the "I'm Feeling Lucky" search.
For example:

Searchblog
http://www.google.com/search?num=100&q=+Searchblog+site%3Ablogoscoped.com&sa=Search

Waxy
http://www.google.com/search?num=100&q=+Waxy+site%3Ablogoscoped.com&sa=Search

Thanks for the comments George. I just updated the page with some amendments...
