I think Zines from nostr:npub1fhmmgwe6fk6tn83ahttt6ruyyfnjdm7k8tn7qflert9ajx6dhfyqf3nzcu are an amazing idea. It would be great if folks did these for all sorts of technical topics and then provide these at conferences or meetups.
Maybe providing a Zine should be a prerequisite for doing a tech talk? So when listeners go to a techtalk they can quickly catch up on a background for that given topic.
