How well Google knows me can be judged by a search for "Omaha". First autocomplete is "steaks" (nope). Second autocomplete is "the Cat Dancer" (yup). The actual Nebraskan city wasn't anywhere in the list (also an accurate reflection of my interests).
@rhorsman not even Omaha Beach?
@saper that was third.
@rhorsman do you know a TED talk by Eli Pariser on the subject?
@saper I haven't, no. I'll look it up!
