I'm not sure what podcast.com was before November 2011, but at this point according to a press release, “Podcast network Wizzard Media and Podcast.com today announced an exclusive partnership to launch a podcast directory designed for existing and potential listeners, with content provided exclusively by Wizzard Media. Podcast.com will feature Wizzard Media’s Libsyn hosting and mobile app products, and it will share in revenue generated from new customers introduced through the site as well as advertising revenues. Wizzard intends to leverage Podcast.com to create greater awareness, content discovery and drive more audiences to Libsyn-hosted podcasts for its producers.”

With more and more people using alternatives to iTunes to manage their podcast subscriptions, I'm curious as to developing another directory, but if nothing else I find this interesting.
