One of the newer entries into the podcast sidelines is PodHive. PodHive is a collaborative wiki which containing information on podcast hardware, software, hosts, and other podcast-related services and tools.
For the uninitiated, a wiki is a a website that is (generally) editable by the general public. Wikipedia is likely the most well-known example of a public wiki. The idea is that everyone who wants to contribute can, and the community will self-police out the imbeciles who just come by to make trouble.
It's been my experience that wikis don't work. Either the idea is only attractive to a select few who bother to contribute and it becomes basically a team blog, or it degrades into total anarchy and the owners shut it down.
Hopefully things will be different for PodHive because it's a great idea. Do your part, go help them out.
