Do you edit your shows at all? I work with audacity once a week, it's amazing how much time you can cut when you edit out extra long pauses, and all the um's and uh's and whatnot.
I did show #1 and show #2 differently. On the first one, I would do the segment and immediately edit everything in each one to cut the pauses, etc. On the 2nd one, I didn't do that quite as much though I guess I still could. When I created the file I listened through it for verbal tics to cut out in the future. (which is something noticeable on many podcasts in their infancy)
I was quite intimidated by Audacity at first...then all of a sudden the freaking lightbulb came on with regards to making cuts and it became a lot easier.
Starting with the 2nd show, I decided that in lieu of a "theme song", I would use the theme from the program I would be covering. Which is a nice excuse to get in that beat from Thriller for WWF 1984-86.
One issue: there's just so much content on Youtube that it's really hard to nail down what I want to do. I do know that show #3 is a WCW show and #4 is going to be 1987 WWF.
