Yes, the update occurred in the middle of yesterday. I also notice that junk sites with the keyword in the domain name are ranking very high. This leads me to believe that this update won't last in its current form. (I thought they reduced the ranking of domain names as to keywords....). My rankings have not changed at all today...hoping they do soon as I have calculated that as of today, down 90% in total clicks. Some keywords though still rank #1 which is strange. If anyone sees an improvement from yesterday, please post here.
