Well, it's now got a home of its own:
There's not much there... The site itself is running NPlanet, but there's no documentation or anything as of yet. You basically just change the Planet.xml file anyways, and the syntax should be pretty self-evident. The default layout is composed of semantic markup, so you should be able to personalize everything from the CSS file.
The only problem I'm having is with caching the page output. Ideally, you don't want to be hitting each and every feed with every page load. I've tried to setup ASP.NET output caching to cache the feed, however it doesn't seem to be working. Help in that regard would be awesome. Anyways, feedback is welcome.
