I'm a little late reading this blog, but the example searches seem fine--searching for "dishwasher reviews" yields lots of legitimate looking dishwasher reviews. The first hit for "iphone 4 cases" had more case models for sale than I thought existed. StackOverflow continues to rank very (very!) high in my search results. I don't recall being annoyed at seeing republished copies of answers, so personalization may put the real SO higher than the scammers for me. (We all get personalized search results, so we really can't talk about a single Google search result anymore.) I have noticed spammy looking republished content in search results of course. Does Google manually adjust search results as people point them out? Or was there very recent change to the spam recognition algorithms?
