When I talk about marketing and nostr I’m not referring to traditional marketing, which most people imagine as PR or some meat space activity. Marketing entails entire product vision communicated in the most effective way. This could mean approaching online communities, having a single place to send people, building integrations, tapping into referrals etc… 

Mastodon and Bluesky both have a place to send people. You can type either into google and see a feed almost right away. Nostr makes you read a bunch of crap and then asks you to make a choice of “client” - not even an app. Small example, but you get the idea.
