i suppose he deserved it, and he didnt seem too bothered by it, but...
he also mentioned that his traffic was going up and so was his sales. so presumably his site was useful to people. more and more people were visiting it, and using it to get what they wanted.
surely that is a good example of positive user behaviour? -- exactly the kind of thing that google is supposed to favour nowadays.
it seems that his rewritten content outweighed the fact that people found it useful.
