At least one of us misunderstood the other, but it doesn't seem worth the time to figure out why and where. We agree that the rationalist diaspora/tribe hasn't mostly migrated to Facebook.

This partially goes to the same point of avoiding overreach -- devising a better way of uniting a diaspora is a much harder task than making LW better.

If you make LW sufficiently better, it may unite the diaspora behind it. If it doesn't, then is it really worth our while to make LW better, at least with proposals of huge changes like this one?
