Popcasts: a directory of the most popular podcasts

This looks useful and interesting:

"Popcasts is an aggregator of the most popular podcasts from many different directories and ranking sites, all on one page."

The webpage consists of various directory listing that seem to reflect the interests of the folks that frequent the various podcast sites. In this regard, I found one directory listing, noted at the very bottom of the page, particularly revealing. The no. 1 podcast on Digital Podcast is "Air America Radio: The Al Franken Show." The second and fourth most popular podcasts, respectively, are "open source sex" and "Pod-Porn.com." Nuf sed. Link
