I do a different type of data analysis (one of my core job responsibilities), not anything web related and each of the points made in the article are so true to the one that I do.<p>At the end of day, I guess, all data analysis is similar, its a tool to discern various aspects of reality (or the truth, if one is more philosophical).<p>And the interpretation of the truth is only as good as the tools used to arrive at it and how well they are used.
