I've noticed there are a reasonable number of Kiwis and Aussies on the Internet generally, at least relative to our population, since our representative numbers would be 0.4% of the Internet population. Of course a lot of the difference there will be due to the fact that we're an English-speaking country with common cultural roots the the US.

I'm not sure why you'd get a large number of Kiwis and Aussies here specifically though. We're more secular than the US or UK (especially in New Zealand) and since I imagine there is a negative correlation between religiosity and the topics Less Wrong covers, that might be part of the reason. I also get the impression that we're less deferential to authority than the rest of the Anglosphere, and I would also expect interest in Less Wrong to be positively correlated with contrarianism, at least along some axes of contrarianism.

I'll send you an e-mail to talk about the other stuff.
