Ask HN: What do you think of this paid content creation platform?

I'm building a paid content creation platform where creators can publish articles, videos, or images to groups. Readers/viewers can pay a monthly fee to subscribe to these groups and get access to the content shared by all the creators of that group (creators can also create their own groups).

You can think of it like Medium + SubStack but not only for writers. I'm still in the validation process so whether you like it or not, your feedback is valuable to me. So what do you think? I also have a Waiting List if you're interested (https://mailchi.mp/1ebc50b72540/lettrify).
