There have been no major changes for the k2ywords I monitor. Please explain why you think there has been a major change in the Google algorithm.

There was a minor shuffle in the SERP's in the last 24 hours and periodically for a long time, but I fail to see how you can claim this as an algorithm change. Google have probably just incorporated new data (ie updated PR and backlinks internally) - that has nothing to do with changing the algorithm.
