> With Facebook's warchest - what do you reckon the chances are of them _not_ buying cellphone location data on the open market to add to their advertising-marketing machine?

I don't think they would have to pay for it. They're just going to give the phone company a nice fat discount on their advertising campaign. That way they don't have to own up to selling your data either, win/win. /s

Mobile phone location data is so valuable that there are whole companies dedicated to 'enriching' mobile phone OpenRTB requests with location data.
