This is great news - I was talking to @diggndeeper.com about making a custom front-end for this kind of thing, though we were talking about walling off the content so you had to be a member to read as well as contribute (probably using custom JSON and encryption).
I thought a bunch about encryption and it's very hard to do on a decentralized way. But nothing says it has to be fully decentralized, it could sit encrypted on the chain and only be decrypted on that one front end. Or alternatively you could keep the content off-chain and use hive/hivemind as an auth and payment system. Definitely lots of use cases there
Yeah we were thinking of it being on a custom front-end, therefore the front-end would handle encryption and decryption using a centralized seed phrase or something, with custom JSON for the encrypted content so regular feeds don't get cluttered with posts that people can't read :)
Having some posts in clear-text would promote the private side with teasers/sample content
