People are very good at understanding value - and even better at parsing the fluff they don't care about - like decentralized nature  or big tech overreach etc. These things concern big voices or developers - not normal users . 

The only thing that is helpful to normal users (so far) is  #nostr offers a single sign on  - but that becomes useful only when there is more to nostr than pure social or social-esq apps  .. spreadsheets  , documents , commerce , travel , research , dating , gambling  .. which means nostr must be a creators' tool before it becomes  consumers' 

Thus there is no good reason to promote it to end users as of now  .. if you build  good they will come ..
