I'll second that for the audio quality (and content). It makes so much difference when you can clearly hear people.
Out of all the tech podcasts I listen to, the ones with the better quality sound are the ones that I listen to first simply because they aren't painful. One that I subscribe to is published in MP3 format at 64kbps, and I really only listen when I've finished
everything else. Which is pretty odd as the guy has some sweet equipment.
Anyways - keep up the good work! Glad to see that they're more regular now!
