GB user Forcen uploaded all the episodes up to sometime in 2008. Fortunately, this download link still works. I had trouble downloading individual episodes but clicking the download button in the top left gave me a 5.96 gig zip file with all the episodes in it.
I had been looking for these episodes for quite a while and am real glad I found this in a 2013 GB forum post. Thanks DookieRope for informing me there is more HotSpot best of episodes than the 2007 episode that is on the This Year podcast feed on iTunes.
