I have said this before, so I'm just writing it here for it to be formally stated on meta.
I have heard from SN admins that the plan is to make SN something of a "digital city". Based on the potential SN has, I propose to understand it as a "digital port", rather than a city: SN is excellent as a first stop right after jumping into the NS, the Nostr Sea. It provides you with a safe and smooth first experience to get up to rhythm to start navigating Nostr, and it can provide you everything to do it: the wallet, the keys, hopefully the logging too for safety. SN would thus be the port from which you can safely prepare to jump into any Nostr client (the ships), to start navigating the Nostr network (the sea).
I really see this abstraction converging and being functional, so hopefully this two sats contribute to SN evolution :)
