I'm a little late to this thread, but I agree with others; the 'meet' tab would be an incredible addition to HN. Perhaps it could include features like location-based topic filters or even a 'looking to meet' tag where users can express interest in meeting others with similar interests. To keep things safe and inclusive, maybe we could have a 'verified meetup' system where members can host and vet events before they’re posted. I'll shut up before my brain dumps all my thoughts here.

On a related note, for any HNers (or hackers) in/around Austin, TX that want to meet, I'd be happy to help organize a meetup in Austin, if you're interested in connecting.
