Blog Network Watch has a list of the most popular blog networks, based on various metrics from Technorati, Google, Yahoo and Microsoft.
I’m happy to note that our very own Web 2.0 Workgroup, which is a loose affiliation of top blogs, is No. 4 on the list behind Gawker, Pajamas Media and Weblogs, Inc. Of course, it’s nice to have heavy hitters like Dave Winer to anchor things.
If you’re not part of a network and want to check out some of your own stats, you can add yourself to the Eh List (http://ehlist.ca/).
Really good list
