As a grader now I've been listening to almost every podcast that comes out. Not necessarily for the job either, I've just realized how great they are on this site. Before this, I really only watched Rich's podcast as he has been the most consistent throughout the years and I like a lot of the topics he brings up/questions he gets. Back in the day (when I first joined the site in s50's) I would listen to Wasty or JoeK's pod every once in a while. There have also been a lot of one offs I've enjoyed over the years.
