Problem with finding similar people with similar preferences in Google's data is that the similarity matrix of any 2 people is very sparse.

I search for Python-stuff a lot, but I also search for stuff related to things I want to buy, or for people, or for my hobbies -- photography and now drawing.

The algorithm for finding similar people is going to have to be very smart (i.e. it should not rely on URLs alone), if at all possible.
