The idea of doing a Patreon is interesting.
The real problem is that from a technology support perspective, this is not a real tech business, it is just a feature on any of the platforms. The moment they implement some type of "Magazines" on YouTube / Facebook / Tiktok, you gotta move from Patreon to their platform because of discovery.
The product is not the tech, it is the skill in curation.
As a curator, i could care less what the platform is as long as someone pays me as much as I can get out of the system. Happy to run it on multiple platforms, on email .. whatever mix pays me the most. But I realize right up front that I will have to be paid on the platform the content is on because that is where it will be easiest to get new sign ups.
