Generally, I'm a fan of the idea of creating social groups that meet in person and are accessible to people who are a little more offline. I will say that you've run into a rather awkward name collision. The Third Wave (when not referencing feminist theory, or surfer lingo) usually refers to a specific social experiment where a teacher created mini-fascism (okay, that's a tldr, but it was an interesting educational thing). Generally it's a great idea though, might be worth a rebrand tho!
