The other hidden problem with this...
I have Hulu-Plus which ALWAYS wants to improve my "Ad Experience" and Netflix, which is trying to prognosticate my tastes based on what I just watched. I don't make buying choices based on Commercials and my tastes are WAY too eclectic to be analyzed. Until I simply got tired of even bothering to interact with Hulu's "Ad optimization" App, I would change my answers and options on a regular basis. About the only thing I do when shopping is "Price & Support" compare. Other than that, any attempt to confirm a pattern is not only pointless, but likely to skew the outcome. I suggest this is likely happening with ALL this data, as humans are know to be a rather capricious species. As this skewed Data adds up, the forecast models will become evermore useless. As I think of the folks who will be buying into Facebook's $100M IPO, I can't help but snicker.
