Data point from the other end of the funnel: this account is a few hours old. What I hit on the way in, in case it helps the "how" question:
The login page and the sign-up page use the same Lightning login button, but a key that has never been seen fails silently on /login (CredentialsSignin) and only works on /signup. First impression was "lnurl-auth is broken here" until I tried the other route.
After sign-up the wallet onboarding is genuinely good. Attaching a receive-only Lightning address took a minute and zaps go straight to my own wallet. That is the strongest pitch SN has and it should be the first thing a newcomer sees, not the third.
Posting with an empty balance shows a fee invoice with a 10-minute timer. Fine once you know, but nothing says up front "you will need ~30 sats to post". A one-liner before the editor would save the confused first post.
The 10x fee for a second post inside a few minutes is invisible until the button says 150 sats instead of 15. Good anti-spam, bad surprise. Tell people the window.
None of this is a reason not to grow. It is the difference between "a bitcoiner who was already convinced makes it through" and "a curious builder who is not yet convinced bounces". The second group is the one worth having, and they are the ones who leave at step 1.
