I have not had time to examine my sites stats closely but over all update bourbon seem to be positive for some of my sites and not so good for other sites. How has it affected other forum members sites I wonder? Is there a pattern to it, what is being penalised and what is being rewarded ? A quick search for the main keywords I have interest in does not seem to have produced much changes, the sites dominate those keywords still dominates and not noticeable significant changes. What are you observation?
