"Being the biggest fish in the aquarium has its ups and downs.  If you are having a \"bad scale day,\" all the viewers will notice it pretty easily.  So when Google's search results change dramatically, especially when focused towards a particular niche, someone will be sure to write about it.  For example, the recent blog post at PBS (yes that PBS) blog MediaShift discusses that just after Christmas... a Google bug made a handful of influential sex blogs \u201Cdisappear\u201D from Google search results. The article links to a good post by Danny Sullivan, circa 2003  and titled Google Dance Case Studies.  It also has an excellent interview with him on the current \"blip,\" which Danny theorizes: In this case, it seems like Google might have been tweaking porn filters somewhat.So the forum connection to this topic is thanks to WebmasterWorld, where a thread was started to discuss the PBS article.  This thread has become much more than a discussion on algorithm tweaks and blips, as WMW administrator Tedster introduces his theory that there is a lot more than just a few minor things going on at Google at the same time to just be coincidence.  He cites over a half dozen threads at WMW discussing issues with Google, including:\nAdWords disruptions \nAdSense Outages \nWebmaster Tools Reporting Issues \nIncreased \"URL-only\" Listings \nSite Root Pages Disappearing \nThe 950 Penalty Increases \nFalse PR 0 Reports \nURL Removal Tool Troubles (he links to each thread)  Tedster feels that We don't see a clear picture yet, but these disruptions to normal operation, all occurring at about the same time, seem like they might be related to a bigger picture of some kind.  Catch up on the sex blog story in the links above and then join the discussion(s) about Google at WebmasterWorld forums."^^<http://www.w3.org/2001/XMLSchema#string>
