At Podcamp Pittsburgh 2014, I offered a session on podcasting using Google Hangouts on Air. If you are unfamiliar, Google HOA is a video solution that allows up to 10 participants (but unlimited viewers) simultaneously which is then streamed.
This session discussed why you might consider using Google Hangouts on Air, especially as a podcaster. I also covered how tos, best practices, and even ran a live HOA. Lastly, we discussed how to take a Google HOA and bring it down to an audio or video that you can repurpose for your podcasting RSS feed to distribute to iTunes and other podcasting distribution points.
