According to Technorati, WorldCAD Access is the #2 independent CAD blog. (When CAD vendor-sponsored blogs are included, this fine blog drops to #4 according to the Technorati method of measurement, but remains in the #2 position according to the Google PageRank style of measurement.)
Here is how incestuous this gets. Guy Kawasaki writes about how little $$ he makes blogging. I post a comment on what I make. Franco Folini reads it, and writes a post about how CAD bloggers rank. I read it and find out I'm #2/#4. In return, I thank Franco and get to mention Guy.
That must be why I try so hard.
