Yes, we're still active. A typical meetup is 4-6 people discussing rationality and other random topics, and perhaps playing rationality-oriented games, for about four hours. The full schedule and mailing list are on the meetup.com page. The next two are on Thursday 21 Apr at 7:30pm, and Sunday 1 May at 2:00pm. You should come, we'd be glad to have your company.

Unfortunately I think that almost any restaurant or coffee shop will be crowded. It would be best if we could get a room at Harvard or MIT, but failing that it is possible to reserve a room at the main branch of the Cambridge Public Library. It would be worth looking into for future meetups, their info can be found here:

The Sunday Cambridge meetups, which happen on the first and third Sunday of each month, are now at 2:00 pm at Cosi, near Kendall Square. As discussed at the last meetup, we've changed the location because the old location was becoming too crowded, and the time to allow the meetup to go on longer before people have to leave.
