When real money is involved on the internet the worst kinds of stuff results, and it takes a lot of effort to avoid it. How's that going to work?
None of this is to take away from your accomplishments here, by the way. The exact opposite in fact, you've got an interesting enough idea that it prompts interesting questions of the mechanics.
P.S. do you have any long-term plans to IPO this if it becomes successful? If not, some kind of guarantee that this platform is immune to enshittification would probably be very, very popular.
This idea more or less surfaces in the book "Fall; or, Dodge in Hell", where in the not-too-distant future the internet is so polluted that you are pretty much expected to hire a full-time "editor" to curate your social media feed. This doesn't scale particularly well, of course, so in reality particularly wealthy families hire an editor to present a cohesive stream of social media to their whole family-tree. Meanwhile the masses typically subscribe to an "off the shelf" stream (or several?) that most closely matches their tastes.
