When you realize you can login to anyone's Npub in amethyst and watch what they are doing, it's like spectator mode, I still advise against it though, feels invasive even with my own company Npub. 👀

You're not logging in anywhere. npub is not an account.
Yeah, but you can look at everything going on in their account.
When I first heard about Nostr, I watched the npub of the guy who told me about it for about a month to see if it was worthwhile. It's a handy feature, given the steep learning curve to get set up.
