GM. Yeah, we decided to tie specific relays from independent operators into our clients, as defaults. Users pay us and we pay the operators. If someone wants a custom instance of #Alexandria, our suppliers help them get their custom relay setup, and they then also pay the suppliers. That way we carry the cost, and they can focus on the administration and security. We're using relays from @npub10npj...tl5h and @semisol. And, of course, we encourage everyone to run a personal relay as a data store, like nostr-rs-relay or #Citrine 🍋 (for mobile). That way, they have their own archive and can use the functionality offline. It makes a lot of sense to store your #ebooks on your phone or tablet, for instance.
