Simpler onramping means more interactivity. It took me 15 minutes and only 2 or three self taught moments to get a nostr web client going fully with metadata (sans zap) on a web client from knowing zero about it, so thats pretty good, considering the RTFM culture in dev. It would be better if appdev folks could package all of this up in a bundle in one place and give extremely good guidelines. Yes, smart people will figure it out, however there is a lot of impatience out there, even among those who we'd like to be a part of this.
In addition, I think web clients are a crucial part of the ecosystem to provide access and third party tools. Relays are still a bit gray in terms of which ones to look at, to join and etc so some sort of directory with details (yes I know there are directories, but few details exist with which to make choices) would be another improvement.
Basically the "M" part of "RTFM" should be better :-)
