Onboarding legacy apps to Nostr is not as much a challenge as an opportunity not taken … yet.
The opportunity to reduce their regulatory footprint WHILE gaining access to an integrated social network AND safeguarding against market dominance from big socials, simply by releasing control of user data WITHOUT ever loosing access to it … will be pretty tempting once they learn about it. 👀
