I think the challenge is that these screens are asking people to join a protocol instead of try an app. 

None of them are bad per se, but most people are not looking for a protocol they are looking for a tool to solve a problem or entertain themselves. 

I think Nostr is very appealing to developers for good reason. What users want is a set of apps where they have one identity but can post different types of content without needing to recreate their social graph over and over. The sell is the set of apps rather than the protocol.
