CK does a great overview on how tags work on Netscape on the Netscape blog.
Tags are in this format:
http://www.netscape.com/tag/ipod/
Every Tag has an RSS feed
http://www.netscape.com/tag/ipod/rss/
… and RSS feeds include enclosures so you can add them to iTunes (or other Podcasting software for the .0001% of you who use something else!).
Subscribe to this rss feed if you have a huge hard drive:
