Apple's RSS

You probably didn't know it, but Apple is providing RSS feeds for most of its important data here on the Apple RSS Information site. Any user can subscribe to or find RSS feeds for anything from the hottest downloads from the iTunes Music Store to Mac OS X downloads by category.

In terms of the iTunes Music Store information, Apple providing this information via RSS is very interesting and shows how the music industry is forever changed -- people in the music industry had to (and still have to) subscribe to the Soundscan service to get weekly totals of CD sales, while Apple freely provides to-the-second information. Even better, Apple provides the iTunes Music Store RSS Feed Generator that allows anyone to customize a RSS feed to include the information that they want to see (you can't do that with Soundscan).
