The change I want to see is a nostr 2.0.
I think nostr 1.0 is finished, to be perfectly honest. It cannot scale. But much good stuff has been developed, many valuable lessons learned, now is the time to hard fork and launch a protocol that can actually scale to a non-trivial number of users, and a number that could support these innovative kinds of business models.
Worth spreading that idea IMO.
Hey! Good point. We will add it. We actually will be adding generic file uploads of any kind, so rest assured PDFs will be supported as soon as we can roll it out! Thanks!
