Remember Big Data. Yup, we dismissed it as the playtoy of the rich and famous (advertisers). Well, Facebook and Google are rich and famous, and they have figured out how to use you.
Remember: If its free, you are paying for it somehow, either directly or indirectly. And if you mind, you better dump your facebook account and bury your head in the sand.
You can’t have it both ways. Ever!
