I watched a prior NOSTR video you made that was great. I'd like to see a NOSTR basics video for the newbie (like me). For example, I've already used my private key to sign into a few clients only to learn that you should never sign in that way because the developer can take your key (makes me wonder if I have to start over). I'd like to know what clients as best for what purposes (and if there's an advantage to opening multiple or separate accounts like I see some accounts doing with Olas), if notes can be deleted or edited, if groups exist (and are functional), if NOSTR can be used to send private personal posts to friends (like a friends list), how private DMs actually are, NOSTR etiquette (GM GM GM ...PV repeat), how to block users or comments (like porn), buying sats for the NOSTR user specifically, and maybe some of the features that you see coming down the pipeline. Just some ideas. Thanks for what you do.
