This is an experiment. I used free Google Hangouts On Air to record and broadcast this live just a few minutes ago. The recording is available on youtube at the link above. Obviously, no one was likely to have realized that there was a live event in time to join this public hangout but in the future I might schedule an event and make that known here at my written blog.
Google Hangouts On Air permits up to nine others to join simultaneously. As moderator I can drop someone who is disruptive and even ban that person from future participation.
This could be a better more dynamic medium than the blogtalkradio thing I did for a while:
Let's see how it goes.
