I find I use
Wordpress a lot as a general CMS for content sites, where I want to just post up news and information (the news and reviews section of this site are powered by Wordpress).
I'm growing warm to
phpWordPress, which is a different application entirely, and seems well suited for article publishing - only problem at present is that you can't assign multiple categories, as otherwise it would make for a superb piece of software for a news portal.
