If we only used immediate fundable projects as a guide for what to build, there would be no Nostr.
Discussion
The linked article describes Jack Dorsey's donation of ~250K$ to Nostr projects.
250k$ can buy approximately 1 year of work of 2 experienced developers. That's not very much and is practically nothing compared to the work required to build all the "Nostr software" live today.
Nostr was built mainly on belief, and I personally like the result.
2 good devs could write better apps in a year. Most of dev effort is wasted on zap bullshit.
You also can hire much cheaper devs from India and Eastern Europe.
Relay development has completely stagnated, no updates in a year for 2 most popular ones.
We differ on those points, but it's too complex (at least for me now) to prove them right or wrong, so I think we will leave this at that.
Thank you for the advice and for telling me about Neo4j Database.
Welcome.
I don't see how you're not aware of the fact that Nostr obviously failed as social media. Fedi is a much better domain for your project because of Threads.
Your project will not be well received because fedi and nostr users don't want to be easily searchable.
