koan... i think that is a great point... those of us who initially reacted to this algorithm update by pressing google to do its quality analysis on a page-by-page basis, were not thinking about the incentives that this would send out.

if google were somehow be able to judge quality on a page-by-page basis, there would be no disincentive to publish a lot of crap on a good domain... now, in the new world we are in, there is a massive disincentive to adding mediocre-quality pages to a good domain. this is going to help reduce the growth rate of pages google has to crawl.
