I use WordPress, both the .com free hosting and the plug-in on actual paid hosting. WP has a crazy amount of plugins that you can do pretty much whatever you want with a basic theme on the hosted version. The free version is enough to get news out there (see the SWR blog).

As for hosting, I use JustHost for the business pages I've set up. The price is decent and they have some easy-to-use tools for your domain email and backup. And WordPress (and other formats) is just a button push away from installation.
