Use rumors to allow non-nsec users to post content. Using a generated tag that way you could allow them to interact digitally during a keynote, workshop or the like. Comparable with mentimeter. #grownostr #ideastr
I think if you want or need to post content on Nostr, you can get your nsec without big difficulties
Yes, but during a college or workshop you might not want to bother your audience with the onboarding proces of nostr
Any client first step is "login" or generate nsec+npub. And it ready to go - welcome to nostr mafrend. What could be simpler? And if you use it temporary for education, just forget it and later generate new key pair if needed. No "onboarding process" need in this case I think.
