You can have more than one distribution channel, e.g. your own monthly subscription site, plus a bundle of transcripts (reformatted as an ebook) + a package of screencasts, sold via https://www.softcover.io/ which takes 10%. Use 80/20 rule to figure out which topics are in high purchase demand and could benefit from a deeper dive. Lower-cost channels can feed demand for deeper/premium products/channels.
Thanks for all the links. I will definitely be checking this out! I had watched Nathan Barry's screencasts with Michael Hartl, but I didn't know he was active on HN, these links look pretty good, so I'll want to read these over! Thanks again.
