This site I just made, GreenMethods.com, might be a good example of what WordPress can do when put into service as a content management system (CMS). This site is over 200 pages, fixed home with separate blog, shop, the works really. I used WP 2.0.11, a few custom scripts, and 13 plugins. The whole thing is valid to strict and AA accessible (including the custom shop). Print and handheld style sheets included. Built upon the framework of my BeastBlog v2 theme.
