The meetups are ongoing! We've had meetups for the past 50+ consecutive months with no interruptions, although we had to be outdoors and sparsely distanced during quarantine.
This whole time? Man, I haven't been looking hard enough. What's the algorithm, 2d Saturdays at 1900?
They're Saturdays at 19:00, but not necessarily the 2nd weekend of the month. We kind of just poll the attendees at the end of each meetup and find out when people are available next month.
The monthly Slate Star Codex discussion meetup. I recommend bringing an opinion regarding a recent SSC post, but it's optional. We have snacks!
