Many cities have regular Astral Codex Ten meetup groups. Twice a year, I try to advertise their upcoming meetups and make a bigger deal of it than usual so that irregular attendees can attend and new readers can hear about the meetups. This is one of those times.

This year we have meetups planned in over a hundred and eighty cities, from Alberta, Canada to Wellington, New Zealand. Thanks to all the organizers who responded to my request for details, and to Meetups Czar Skyler and the Less Wrong team for making this happen.

You can find the list below, in the following order:

Africa & Middle East
Asia-Pacific (including Australia)
Europe (including UK)
North America & Central America
South America

There should shortly be a map of these meetups on the LessWrong community page.

Within each region it’s alphabetized first by country then by city - so the first entry in Europe is Graz, Austria. The exception is the USA, where they’re also alphabetized by state - so the first entry in the USA is Huntsville, Alabama.

I’ll provisionally be attending the Berkeley meetup.

Extra Info For Potential Attendees

1. If you’re reading this, you’re invited.

RSVPs are mostly to give organizers a better sense of how many people might show up, and let them tell you if there are last-second changes. I’ve also given email addresses or other contact information for organizers in case you have a question.
3. If you have any feedback on the meetup (compliments, complaints, curiosities, etc) the feedback form is here: tinyurl.com/acx-meetup-survey .

Extra Info For Meetup Organizers:

1. If you’re the host, bring a sign that says “ACX MEETUP” and prop it up somewhere (or otherwise be identifiable).
2. Bring blank labels and pens for nametags.
3. If you’re having trouble thinking of something to talk about, the attendees probably also read ACX. Ask people about a recent post or book review that they liked.
4. If it’s the first meetup, people are probably just going to want to talk, and you shouldn’t try to organize some kind o...
