I recently noticed that business podcasts don't seem to be a very popular genre in the podcasting space. I interact regularly with business podcasters and consultants and that makes it pretty easy to get myopic. lt's good to get out and look at your space from the outside sometimes.
Given that Cam was reporting G'Day World as having 21,000 downloads in June and it's at the top of this list, I don't think this list contains a whopping amount of downloads. However, it's interesting (to me, anyhow) that there's only a single business show on the list and it's in last place. Actually, if you've ever heard Wayne Turmel's show, Cranky Middle Manager might be more accurately described as humour than business.
I'm going to start paying more attentiong to lists like this. So far, it seems that music and general entertainment top most of the lists I've seen thus far.
