I'd like to do this very much, and have actually given it some thought already, as several of the podcasts I listen to feature this.
What I'm trying to sort out right now, as we've just started, is whether we'll do delayed response or "within the episode" response.
For example: delayed response is easy: Listeners send questions, and we answer them in the upcoming episode (probably 3-4 max per episode) with de-duplication of questions of course.
Or, and what I think is more interesting but harder to do, do we alert the listeners to upcoming guests, and have them send in questions for that guest to answer while recording the episode. And that of course is challenging. I may start with A and mix in B, but listener questions are on the list of things to do.
The schedule will be variable, for example, episode 2 is already recorded, is being post-processed, and will be published later this week. As much as I'd like to, I can't sustain that rate. So it may happen weekly, bi-weekly, monthly (though I hope more frequently than monthly).
I can tell you that plans for episode 3 through 5 are already laid, and guests are being invited. Again, since we want to have guests and not just make this a 476th event (episode 2 will again be with 476th members), it also takes time to make that happen. Though we've got good responses from some external invitations, so episode 3 will definitely feature non 476th members.
Thanks for the interest!
