Well, people who do research and writing for a living cam find time to do such things. As someone who runs my own weblog, I find that it doesn't take as much time as one might think, assuming that one already is spending a lot of time working on a computer, and can do it in spurts and breaks. He doesn't actually write all that much--he mostly posts short comments about stuff that other people write,and weblog software makes this pretty painless.
I take it "NonZeroSum" is reference to the classic rejoinder to the Hobbesian argument for the State, no?
Actually not--it's more of a reference to game theory, and Robert Wright's book of the same name.
2) Robert Wright is a pretentious bore. Like Tom Friedman of the NY Times, he is much smarter than the average journalistic pundit, but at the same time way way overrated. Only a fews hours after the attacks on the morning of Sept. 11, he's up on Slate.com saying "s=See, see, see everybody, this PROVES we don't need National Missile Defense."
