PodCasting Awards

I have been seeing ads for PodCast awards around the net lately, the site seems to be here if you want to check it out. If you aren't already aware, a pod cast is a sort of radio show over the computer, distributed through RSS and the other XML based protocols usually. The intent is that you download the podcast and put it on your (i)pod to listen. NPR (National Public Radio) has some good ones, but other than that I am fairly new to podcasting. I would be interested in hearing what people like (particularly in science/technology topics) so go check out the contest and/or comment below (I listen to NPR's "Science Friday" sometimes, but that's about it).
