This really reminds me of how podcasts have gone. It used to be that nine out of ten podcasts I listened to had no ads - they were about spreading a message or having fun, or getting some personal recognition. They didn't have major overhead because it's cheap to come on once every week or two and chat with your buddies. Now, not only are there many high-quality professional podcasts, but the old fashioned ones I enjoy have all one by one gotten in on the game. Eventually podcasting became something you either made money at or you were doing it wrong (see also: blogs). When even BackStory and The Skeptics Guide to the Universe are shilling for Blue Apron that transition is complete.
If you're looking for people who are still having silly fun, have a look at Twitch and the folks over at 'just chatting' or I think there's a section specifically for programming? Those channels very much have that informal vibe.
Regarding making money or doing it wrong - says who? The barrier to entry for podcasting has never been lower. It's all in people's heads :)
