Well we definitely appreciate the education. :)
Again, how do you know it is Caffeine? Saying that you see something on one data sets that doesn't rank on two other data sets - how does this confirm to you that this data set is Caffeine? It seems to be somewhat circular logic - a tree is a tree because I call it a tree, but without any previous reference, how would one know this 'new' set is x,y or z?
This was my point with many of the last posts in this thread.
Because the data set contains rankings that were previously not seen, or are different from post Holiday SERPs, wouldn't justify as Caffeine 'by default'
I have seen many different data sets on those ip's. What distinguishes them from Caffeine?
