I see from time to time people mention a 'rationalist house' as though it is somewhere they live, and everyone else seems to know what they're talking about. What are are they talking about? Are there many of these? Are these in some way actually planned places or just an inside joke of some kind?
Expanding on Ben's comment: local lesswrong meetup groups often grow into a communities of people who enjoy spending time together, at which point some of the people might decide to rent a house together.
If it's worth saying but not worth its own thread even in discussion it goes here.
