Some suggestions on 'zero-cost marketing' for Nostr clients and other stuff. Feel free to add on suggestions : 

1. Write more on media - approach various angles of Nostr and target at least 1-2 articles to be published a month. 

2. Reach out to users based on where they are - if college kids maybe have talks or workshops on campuses. If it’s neighborhood, put up short and catchy brochures in the neighborhood local businesses, coffee shops, on the street, bars . 

3. Ted talks or similar highly established talks with a large audience on the concept of 

(a) “reversing the current internet” like how nostr:npub1zuuajd7u3sx8xu92yav9jwxpr839cs0kc3q6t56vd5u9q033xmhsk6c2uc ` talked about or 
(b) bridging many diff ideologies through platforms and bringing people together like how nostr:npub1k979np6dcpwh7mkfwk7wq3msezml48fh7wksp9hakakf8pwk3y5qhdz7te  is doing it . 
These are all very novel concepts.

4. Do short videos like how the Thai tik tok went viral - and post it on various other social media - tik tok, IG, FB. 

5. Partner up with businesses for free onboarding promo on their website to their clients. 

6. Get into as many TV interviews and radio interviews

The current marketing initiatives are heavy on Bitcoin conferences.
 
1. It might be stale because of high repetition

2. BUT. Because it's easier to convert bitcoiner, the initiatives here can be one step beyond onboarding - such as establishing bitcoin relays or if specific to localities, then onboard someone local who can set up local relays and that person onboards more people from there, and it relays on =)
  
Goal = acquire users + grow this user base. 

Some thoughts : 

Having a great and easy to use product with useful features is one thing. Finding users is another. Both are different types of challenges. 

I like nostr:npub1jlrs53pkdfjnts29kveljul2sm0actt6n8dxrrzqcersttvcuv3qdjynqn 's  concept of user growth and I think clients would benefit from a user acquisition strategy, establishing primary, secondary target audience and finding means to engage them. 

I hope Nostr doesn't die off. It's a great initiative.
