This is great!

There are a few minor spelling and typographic errors sprinkled through it. Might want to do an editing pass.

Slide 12 characterizes NIP-07 as "Browser extension integration" but NIP-07 is not nearly so broad. It is only for "Browser extension signing of events," or could just be listed as "Browser extension signing" in a presentation format, since the presenter can elaborate on what it means.

Slide 15 characterizes everything as public unless encrypted. That is not necessarily the case any longer. Everything is as public as the relay it is stored on. So we have a spectrum of privacy levels available, depending on how a given relay restricts read access, and whether notes are stored as plain text or encrypted. For instance, I administer a private community relay. Only npubs that are whitelisted can read from it or write to it. However, it is stored as plain text, so it is not as private as it could be, but it is more private than storing the same notes on a public relay. I could also choose not to have that relay accessible over clearnet, and only give the folks I want to have access to it the onion address, or have it only be a local relay, accessible by my family on our local network, or remotely using Tailscale. Lots of options for enhancing privacy at the relay level these days.

Slide 21 suggests one client each for iOS, Android, and Web. If I may be so bold, I would suggest replacing Snort with Jumble. Reason: Jumble is a better showcase of Nostr's core architecture, because it puts relays front and center. You still have the standard follow feed, but you can also look at a feed of all notes on a particular relay, and create relay sets that show you all notes from more than one relay in a unified feed. I also find Snort to be slow and buggy these days.

FANTASTIC JOB, though!
