Very interesting article :-) I had no idea that the community is this large and that there are only two moderators.
The article could have explained the other part of the moderation better - the user moderation provided by up and down votes. Bad comments are not only flagged but also tend to be pushed further down the page towards oblivion, while better comments tend to be lifted up towards the top of the page.
Anyways, King Canute: He was Danish, not Swedish :-)
