Is community cohesion something to aim for? Ideally, rationality should be the baseline, not the marker of our particular community. As recent threads on gender have suggested, there's room for quite a few different communities which share core principles. Ideally, lesswrong would be one of many places where rationalists of different stripes feel comfortable. Of course, the question is whether it's better off huddling together for the moment in hopes of reaching critical mass or if we're already past that phase.
The only sad part of that story was when the AI died.
I rather like the idea of people creating separate locations without cross-posting. I'd hate to see the rationality community become tied to a single possible point of reputational failure.
