Google recently launched Communities on Google+. These are like Facebook or LinkedIn groups: anyone can create a Google+ Community about any topic.
Podcasters like to hang out and chat with other podcasters. Google+ Communities are a great why to do this!
There are many podcasting-focused communities already popping up, but the following two are the best, most active, and where I choose to participate in podcasting discussions:
The Podcasters community was started by Jeffrey Powers from How to Record Podcasts. This is currently the largest and most-active podcasting community on Google+. I am also a moderator in this community.
The Podcasting Technology Resources community was started by Martin Brossman, who also leads the Podcasting Technology Resource Group on LinkedIn.
