tbh, I was excited at first but it turns out it's too hard to use if you need to create an account with your service for every user.
also, you could consider to make the service free, and allow others to host their version too (if that's not possible yet... or is it?) and then come up with a different way to monetize.
really trying not to sound arrogant. I appreciate the work and think the approach is great. it's a useful idea but the hurdle to start using it and value it brings at the current use of nostr isn't worth it for many use cases imo.
