Request for product: A wallet-connected media platform that would allow me to publish longform work, host AMAs or live-interview kinds of formats (almost like an irregular podcast), and host a community where the main focus is a curated news/info feed. 

The monetization happens in the form of membership. Possibly with different tiers. 

Does something like this exist?

Not yet but many are actively pursuing these goals in a loose, chaotic manner.

You can follow my progress in wrangling these ideas into a platform on /nearchos
