People forget, it's hard to generate value in the long run with something that costs next to nothing.
This is also why StackerNews is a lousy producted and a RETARDED investment, ESPECIALLY at a $25m valuation -- only fiat LARPers could make that sort of investment. 🤡🤡🤡
Why do you expect to write a few lines of code that can be easily duplicated and make billions in profit? Anyway, all of these legacy, closed protocols will be obliterated by Nostr and the profit will be found by people who understand and enhance their user's ability to engage in useful, real world enterprise.
