If you organize a Nostr meetup, make it easier for people to find each other and talk to each other. Nostrautica provides a perfect user experience for that - sign in with your Nostr identity, optionally say something interesting about yourself or who you're looking for (your Nostr activity is enough for most users though) and Nostrautica will match you. Then in person, you either know the smalltalk to start with (Nostrautica even suggests ice breakers) or if you are a cool nerd, just skip small talk entirely. After the meetup, you already follow everyone you met and have a way to DM them.
