The Cambridge, Massachusetts Less Wrong group has 2:00pm afternoon meetups on the first and third Sunday of every month. Additionally, we're having an extra meetup on Thursday evening (April 21) at 7:30pm. The full schedule is kept on meetup.com, and you can join/subscribe to the group there to get e-mail reminders. Meetups take place at Cosi, near Kendall Square on the red line. Follow the right-hand rule to reach our usual table, which is in the back room where it's reasonably quiet (except for us). All are welcome to attend and no RSVP is necessary.
