Having read vanessas article it would be very easy to take it out of context, i dont doubt the algo update would focus on long tail terms, this is one of the main aspects of the caffiene update, they have more resource to handle such. However, the interview was a pr man and his comments were then 'interpreted' they could be interpreted in 101 ways so have to be taken with a very large pinch of salt. It is very probable that the algo change has meant a reindexing from scratch of the long tail onto the caffine system, therefor large sites are taking longer to crawl hence taking longer to reposition.
Traffic in the mean time has gone to the smaller sites which can be quickly reindexed and evaluated. Larger sites are going to take longer.
Until things settle and some reliable information can be obtained, wmt and search correlate or something definitive from the horses mouth then it is business as usual here; quality content, new links etc etc
I am going to make a prediction, sometime between 3rd and 5th june there will be another massive shift.
