podcast

So, for today's entry, we are asked to comment on what constitute a good podcast.

honestly, I've never downloaded any podcasts, however as a medium of expression, criteria for the content of a good podcast should be somewhat similar to the criteria for a good blog entry. The difference is that for the podcast project we are given a very specific topic to follow, so besides being interesting and creative the content has to address the topic at hand.
the other aspect that affect the quality of podcast is specific to the presentation medium. If video is chosen, is the video well edited? camera nicely handled? graphic to acceptable resolution? clear audio?
and for audio presentation and the speakers speaking clearly? negligible noise from equipment?
