I had a business card for this site from when Vinny and I attended a PodCamp in Brooklyn in 2008. There was no name on it, just the domain name We've come a long way since then, but this site has a nice concise explanation of what Podcasting is and some resources for Directories and Communities.

The company running the site is RawVoice, but they are looking for community input to keep the site accurate and uptodate.
