I've been listening to that and The Jamil Show/Can You Brew It(also from The Brewing Network) for quite a while now. Tyler does too. Even has a BN Army T-shirt. I learned more from those two podcasts than any amount of reading I've done by a long shot. Jamil Z and John Palmer really know their stuff. Jamil is a bit cheesy most of the time and John Palmer is nerdy all of the time but if you can get past that they have a ton of knowledge on brewing and Jamil is one of the most decorated brewers nationwide. I'd suggest that all new brewers listen to the attenuation show at the very least.
