By the way, I don't think browser data is driving the results, I think relevance drives things and user metrics (possibly collected from the chrome browser) is like the final quality check that prevents rubbish getting through by demoting low quality and promoting high quality.

Without that quality control the one right answer could all too easily be webspam.
