Bitcoin existing makes PoW as an arbitrary anti-spam measure (like for emails) completely defunct. You could pay a miner $100 to make enough work to send 10,000 spam emails - and that's being generous, it'd probably be far more affordable. 

 Web of Trust is old. Nothing about Nostr indicates Web of Trust will work today if it didn't work before - and by work, I mean scale to meaningful adoption. There are both UX and incentive problems, and both lead to a Web of Trust naturally deteriorating into a centralized model where users trust few monolithic authorities.

Which is exactly what we already have. It's exactly what YOU USED to log onto Nostr, @LynAlden,  you relied on that certificate, which is completely centralized in its distribution and authentication, to get onto Nostr.

I'm happy you are pushing  decentralized tech, and that you haven't been led astray by 'shitcoinery,' but  people running Bitcoin and Nostr nodes as a hobby is not going to get us far past this. 

 This is terrible logic. Any crappy project can use this logic to just suck people dry for years on end. It doesn't mean Nostr can't improve, but the fact that some projects take time should not all convince anyone that something moving slowly can actually get into orbit just because a rocket starts also moves slowly at one point in the launch.
