BN has entertaining stuff, some good info, some head scratching stuff. Like on the Jamil show, the cohost is Tasty and almost every time Jamil asks him if he's brewed the style they are discussing, he has not brewed it... Doc has been judging on Dr Homebrew lately and says things that probably drive real judges nuts, like smelling astringency etc. But, I still listen. The Session has become very commercial beer centric.
Lately I've come to enjoy James Spencer's Basic Brewing Radio. It has an NPR feel at first, but the general atmosphere is much more friendly and light hearted. Might go so far as to say "grown up" as compared to the raucous frat house style of the BN.
Of course Experimental is a go to.
