"stale" documents... may be ranked higher than "fresher" documents
I seem to remember a recent thread, in which scraping was discussed. The consensus was that google uses the age of the document to figure out who the scraper is. It was also concluded that if you update your page, google resets the age, which can land you in the supplementals while the scrapers get the glory (because their page is older). If this is true, then there may be a tradeoff for webmasters of holding onto proprietary content versus freshness.
