"An early WebmasterWorld thread is reporting very early signs of changes taking place at the various Google data centers.  Often, these types of threads tend to spot a Google update that is about to take place.  But it would be cool if Google gave us a Valentines Day update.Let me stress, this is very early and that Google always updates their results - daily.  But this seems to be a larger update.Here are some of the reports from the WebmasterWorld members:A well known rank tracking service is showing a huge spike of changes for yesterday. Looking at various datacenters it looks like Google is \"testing or comparing\" different series of SERPS, at least for the keywords I'm tracking: September set of results, late october, Christmas time and January's SERPS. Perhaps Google is comparing the filter/penalty/alogo changes we have been seeing against its results from pre-September. Again, it is very early, but I will track it.Forum discussion at WebmasterWorld.Update: Matt Cutts commented below that he does not believe there is an update taking place.  Plus, he has a room of SES speakers who backs his opinion.  :-)"^^<http://www.w3.org/2001/XMLSchema#string>
