Off-topic: I wonder why the site insists on using the super long domain name of "therubyonrailspodcast.com" when (presumably) they own "railspodcast.com" since it redirects to the longer url. Even if it's for legacy reasons, it seems like podcasts of all things would be the easiest to 301 redirect (the longer url to the shorter).
