I'm making a site for a client, and I'm using wordpress (the blog software) for the news section of the site. I shoehorning it into an existing site layout which essentially means building a theme from scratch. Not that hard, just tedious, especially when said site doesn't include a sidebar, which is a fairly integral part of most Wordpress layouts.
On the plus side, if this works, then I'll implement it on the Exilian site and staff can post news articles without needing a degree in XHTML.
