nostr:npub1pzzrdngrnlufqazx3lfj07k0vfuya6ehfy8q5yv2h8c5e8fxgmxqhxdsr8 immediately asks the most important question imo. Do we ultimately need "pay to post" incentives? Will this be solved by other emergent business models (as we're already starting to see from companies like nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg ). My intuition is that other business models will subsidize and keep the network sufficiently decentralized (ie enough relays storing notes).
I also think that Nostr is more about the identity layer and ability to find peers or other communities via relay rendezvous points, at which point you can use whatever transport layer you want.
But we'll see... Probably the biggest open question in my mind. Wdyt?
