BTW we all know there isn't an RSS 2.0 feed, it isn't a podcast, but rather than getting all preachy, which no one likes, mention a "podcast feed" as a real thing that's expected. Always add "feed" when you say podcast.
The feed gives you and podcast producers the thing that makes podcasting so different -- freedom. For listeners it means if you don't like something the software does, you can switch without losing anything. And for producers there's no one who can stop you from speaking. There is always a way around a blockage. But only if there's an RSS feed.
