I'm allergic to new periodic posts but that is a good idea. Will think about it.

Helping people to make more real-world connections is a thing I'd like HN to do more of.

That would be really cool, I'm sure a lot of people (including myself) have never heard of an HN meetup or knew they existed. This thread is building community, and seems really cool. If there was one resource where all the meetups were consolidated, what better place to do that than HN itself. Something like the github list posted by anton_tarasenko[1] but in the menu bar would even suffice fairly well IMO.
