Tune in to our Podcasting blog where Jeff De Cagna's polling readers for their take on the "art and science" of what makes a compelling podcast.

Among the comments so far: "Whereas traditional broadcast media serve geographic communities, podcasting serves psychographic communities. Due to production costs, television and radio programming must serve communities that are large enough to be economically viable (in a marketing sense). Or their production costs must be underwritten. But podcasts do not (necessarily) have such large production costs, thus they can be 'viable' on a much smaller scale and for much smaller communities than is possible with traditional entertainment or information programming."
