OpenPodcast.org - The ‘Open Mic’ Podcast

Intruiguing concept that would automatically promote your podcast to its 1500 subscribers - you send five minutes of content to the address on the OpenPodcast.org homepage. I haven't had the chance to listen to it yet, so I wouldn't suggest sending in talk format... in fact I'd suggest you have a listen before you send anything.

Here's a quote from the site.

"OpenPodcast.org is a dynamically generated podcast to which anyone at all can contribute. It expects 'short' segments (under 5 minutes is suggested) which will be included in the feed as they are received. Think of it as an audio wiki or time-shifted unmoderated call-in show. "

Sounds like fun.
