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.
