So, since I built this market research tool earlier today, I felt like playing around with it. One question I had was "What mental worlds, according to Facebook, do men and women in the US inhabit?" and "Do they intersect anywhere?" Well, see for yourself. _Women_ in the US gravitate towards the following brands, personalities and services...  ...while _men_ in the US gravitate towards...  Interestingly, when comparing the two sets, there are _no shared interests_ among the top 50 liked pages. I had expected at least a few brands to appear in the middle.  Anyways, just a quick note really.
