To be honest, I didn’t find this particularly surprising since I assumed Google had long been doing this.
But the winning quotation from the press release was this nugget:
Our recently launched personal search feature is a good example of the cool things Google can do when we combine information across products.
Of all The Web’s sentiment I saw, “cool” was not among it.
Unless you by “cool,” you mean “incredibly creepy, of limited actual use, and full of chilling effects.”
Does this change fall under “doing evil?”
I suppose it depends on how they end up using the data (and whether or not any independent entity could ever audit those statements to assert truth)… but however they use it, I’m pretty sure it will result in some pretty epic unintended consequences.
