Ron Moore is also posting audio commentary on
Battlestar Galactica episodes in MP3 format. As of this writing, the commentary for episode 9, "Tigh Me Up, Tigh Me Down", is up, along with instructions on how to play it along with the episode. I haven't listened to this commentary yet since we haven't gotten to Episode 9.
(If you aren't familiar with the term, the Wikipedia says,
"'Podcasting' is making audio files (most commonly in MP3 format) available online in a way that allows software to automatically download the files for listening at the user's convenience." In this case, you can also download the file a la carte.)
I'm very impressed with the way Ron Moore is embracing the Web to improve fans' enjoyment of the show.
