Someone should build a nostr calendar. Things like #nostrica or the #zapathon that #[2]​ is organizing - would be cool to be able to get reminders of stuff coming up or even register for events. Give people more connection points that they wouldn’t always have otherwise.

Could require zap of X to get reminders/register/create event to avoid bots spam. Filter by date/event type. Once live streaming is a thing (will be dope) you could schedule your concerts, talk shows etc on it.
