> search results biased by my previous queries

would that have to be a bad thing? I understand it prioritises search results near you area, or remembers things like whether you're more into the country or the animal when you search for [turkey].

I think concerns about the online filter bubble can be a bit overblown. We have the same thing in real life too: e.g. I like to hang out with people who share my world view rather than seek out those with opposing views.
