...and then there's Across the Sound. I've never been a big fan of podcasts for 2 reasons:
1 - Most are boring as hell, IMO.
2 - Since I am the last living person on the planet with dial-up, it takes me approximately 2.7 days to download a 30-minute show.
But I must say, the couple of times I have spent the 8-10 hours necessary to push 10 mins of ATS through my modem has been time well-spent. I'm listening to the first 15 mins or so of ATS: Episode 36, and it all started with Joe's description of the show (see if you spot the hilarious joke), and so far he's plugged several other podcasts, then he acknowledges that he's creating more competition for himself, then clarifies that he has no problem with that, and then plays several listener comments. Of course he then makes the mistake of letting Karl Long make a comment, which lasts so long that the answering machine has to intervene. Still, Karl and Joe have a hilarious, and spot-on account of SethGate, and even mention Hugh's 'response'.
But anyway, definitely give Across the Sound a check, my guess is that once you hear the first show, you'll be hooked and immediately dig through the archives looking for more.
