My project Freedirectoryguide is now live. The website can be viewed at www.freedirectoryguide.com.
This website is an example of how WordPress can be extended to integrate with other databases outside its own internal structure. Most of the content that you see is provided by CityGrid Media and is accessed through api calls. The categories, sidebars, theme, and page structure is provided by WordPress and Genesis. The architecture creates a shell that is easy to manage and extend. The shell also provides hooks for SEO.
