Top Blogs For Term (.NET Weblogs Archive)
I'm working on extending the archives to do some useful stuff with all that data, now that we have a good amount of data to mine. You can preview the first of these features here:
http://www.activehead.com/dotnetweblogs/TopBlogsForTerm.aspx
This page will allow you to find the top blogs for a given term and show you how focused that blog is on the topic you choose (for example, Scoble tops the list with something like 285 posts about longhorn, but they only account for 8% of his overall content, while Chris Sells comes in with 66 references, or 16% of his content). Archived feeds will show up as having the URL www.activehead.com right now, since that is where they were imported from (need to run some updates on the DB to update the blog locations for old posts). However, it will also list the author, so a quick google search should do the trick for now.
