Feedster has refreshed and improved its list of the Top 500 blogs, and you can now use a tag-cloud to group similar blogs together. Engadget is still top of the pops, ahead of Boing Boing and TV Squad. The once mocked Huffington Post is in seventh place.
I'm amused by the fact that usability guru Jakob Nielsen's not-a-blog Useit site is 52nd on the list, well above trendier players such as Andrew Sullivan (73), Michael Moore (74), Robert Scoble's Scobleizer (76), Dave Winer (92), Kuro5hin (111), John Gruber's Daring Fireball (124), Lessig News (145) and Doc Searls (149).
Update: There's also a blog post about how the list was compiled.
