To anyone who knows: How active are the fortnightly Cambridge, MA meetups? There seem to be very few RSVPs on the meetup.com page, but I suppose it's possible that if there are any regular attendees they don't always bother RSVPing.
We generally just don't bother RSVPing. Median attendance is 4, occasionally much more.
It seems we have agreed that open threads will continue but that they will go in the Discussion section, so here's this month's thread.
