Sounds like a good meetup. Next time, I hope. (My wife and daughter are both unwell, and another commitment has me abandoning them both for most of tomorrow, so I really couldn't justify disappearing off for hours today.)
Given that there were around a dozen participants, it's pretty clear that it's worth having a next time.
Being curious about the number of LW readers in Cambridge, I propose we meet next Saturday afternoon, 2pm February 12th at The Anchor (12 Silver Street).
Feel free to suggest a better time or place if this doesn't suit you.
