syndication feeds not working

Keep in mind I’m relatively new to blogging software and syndication. I’ve begun a WordPress 1.5 blog at http://goodmorningcaptain.com and the links to the feeds so that one could syndicate it don’t seem to be working. As a test, I’ve tried using a variety of feed readers, but to no avail. Is there something I need to do to get them to work? I have done nothing in the way of any hacking of the files, they’re pretty much as-they-are since installation.

Any thoughts?
