Regarding point 3, we believe that future relays will add support for storing multimedia content, as Cashu sat can solve the issue of storage payment.
quoting note1wcn…6v32Tried #keychat for few hours and it's working very very well, smooth experience and nice UI.
I like the options given so far, like the choice of using Signal protocol or NIP4, although as of now Signal protocol is a no brainer because of better privacy
So far I've realized a couple of things:
1) Paid relays are probably the future of #Nostr, if the protocol will gain the mass of users the hope
2) Using Nostr relays for messaging is a nice idea, particularly if the amount of relays will increase in the future (already tens out there), because of the neutral position of relays with regards to nodes, particularly Kind1 notes
3) In private messaging apps we're used to send also multimedia content, which is a bit more tricky to deal with if you aim at keeping the #Nostr protocol distributed enough
4) mobile texting today is made of apps that don't charge for the messages amount, so people are used to sent a gazillion messages of few words. The pay-for-message paradigm would completely change how we approach texting.
Paid messages and relays help me realise how low is the profitability of LN routing, btw...few hours of messages and you wipe your monthly average revenue from routing XD
