Websites — this is a great list of the best sources and answers for your WordPress site. This is the revised third edition according to the author.
Excerpt: That provided me with enough impetus to start from scratch. I felt that, in order to provide a resource of true worth to WordPress enthusiasts, I needed to be more ruthless with the list, and also offer up some additional context to point people in the right direction.
So that is why this newest edition of the WPMU 100 is in fact the WPMU 40. I have slashed 60 sites from the original list, based upon merit alone (as opposed to previous rankings). Furthermore, each site has been reviewed and can be filtered by four categories:
News: the latest updates regarding WordPress itself, and WordPress products/services
Reviews: coverage on themes, plugins and services
Tutorials: guides and how-tos
Dev: resources for WordPress developers
