Good point. Also in most situations data collection goes far beyond 1,000 customers at little to no additional cost. This doesn't necessarily break the author's point though since if there was tremendous value to this data, programs like Google Analytics wouldn't be free. The fact is that most of this data is worthless. You get most of your value from one or two data points that you chose to quantify a qualitative goal. My perspective comes from my first market research job where I was hired to "make sense" of Nielsen's data for a TV series. It was a cop-out on the company's part - a trained high schooler could have done what I did, organizing thousands of numbers to recognize the 4-5 key takeaways to present back to them. I think the intimidation of large sets of data often tricks people into thinking they're more valuable then they are, and as data collection intensifies, so does this fallacy.
