I have a started a new Science Podcaster's Community over at Google +. I promise to keep it as low noise as possible and focused on the needs of people who podcast because of their passion for sharing the scientific quest. Space podcasters are also welcome. If you are thinking about starting a science or space podcast, you are also welcome to join in.
Note that this will not primarily be about podcasting gear. Audio equipment is fun to play with, but I think that podcasting is almost all about content, and that is where this community comes together.
