I was excited today to see that Watching paint dry moved from #12 yesterday all the way up to #1. I threw a party, emailed Alek and took a screenshot of it. Well for the first time ever it happened to me. I have never had personlized search move results more the 1 or 2 spots. If you look at the SERPs with personlized search of the results are similar, but with watching paintdry at 10th through 15th. I changed DC's and the results were all the same. With it on we were golden, with it off we were less than golden. From what I saw changing the UI did nothing to the actual results. So how many of you have seen such drastic changes in the results from the use of personalized search and what were you searching for?
