It's a matter of perspective, a lot of people love the brewing network and their inane chatter...me personally, I'm to old for it...The shows on there, despite having Jamil on it, drive me nuts...But it's different strokes for different brewers I guess.
My two favorites are
ANd the oldest Brewing podcast (out of Australia, it started as radio over a decade ago, and the hosts have 60 years of brewing combined..) Craftbrewer Radio
Basic Brewing is a tight, single topic show...very slickly done (the host is a proffessional voice announcer with his own production company)
The Austrailian one is Chatty, and they cover a lot of stuff in a show, BUT they talk about and do some pretty amazing techniques. AND after spening Christmas break listenning to everything of theirs in all their archives (some are on a different website and go back to the radio show days) It turns out that when they first went online some guy in America named John Palmer used to listen all the time and email asking them questions....a few years later they realize that the John Palmer learning from them, was THEE John Palmer of How to Brew fame...
