@xcoder: I didn't mean information source, I meant information. What information is in my browsing history that would tell Google my next search is for something I want to buy? I very rarely order anything online (if I find a supplier, I phone them: I don't want to buy anything from someone I can't gey hold of if there is a problem).
Search phrases tell them more, but even there they can't always easily tell whether "widgets" means I want to find out about widgets or whether I want to buy one.
It seems far more likely to me that Google are trying more and more radical methods to manage a mountain of content that is growing at an almost (and I am not even sure about almost) unimaginable rate. What concerns me most os that they are getting it wrong, not that there is some sinister intention to destroy my livelihood.
