Precisely, for instance Discord runs in app events were you can earn rewards, badges or sats, Slice allows you to answer surveys, vote on various topics, questionnaires and also earn sats, Sats4Likes allows you to like, re-post, comment on Posts and earn sats. Bitcoin Magazine and Simple Bitcoin allow you to read news and earn sats. So i think many strategies could be implemented in which users would interact with this app and earn rewards for doing things unrelated to #Bitcoin or #Nostr.
