D&D Podcast
I started using a new capability of del.icio.us which allows you to tag audio files and create a feed from that tag. del.icio.us automagically adds the enclosure tags needed to podcast those audio clips. Lots of people have already written about it.
My first project using this new capability was to create a podcast from my Friday night gaming sessions. We’re playing 3rd Edition D&D (3.5) and my friend is running his Azzuria campaign. The sessions are documented here. Each session usually has a map that tracks our progress across the land of Azzuria and usually contains a tactical map we use for combat.

I wrapped the feed with Feedburner so I would get all sorts of extra goodies that Feedburner is good at giving: iTunes tags, stats, ability to add a logo and extra metadata to the feed.
The del.icio.us base feed is here:

However, I recommend that anyone who is interested in this madness to subscribe to the Feedburner wrapper feed:
If you use iTunes, just subscribe and go. It's not that fun to listen to these outright. We use them mainly to go back in time so we can remember what kind of treasure we found, or what a character said during an encounter. To manage that, I use a Konfabulator stopwatch to record the time offset in our campaign notes.
