Who's data is that... really?

Propublica has a fascinating article up on the location data your cell phone provider tracks and what they do with it.

The thing I found most interesting was they'll give it to lots of people, with one major exception:  You.

It's worth taking a few minutes to read if you have a cell phone with GPS capabilities (which is, very likely, most of you).
