'Dataclysm' author Christian Rudder argues Big Data online is changing history
A facebook "like" here... a deleted message on a website there. Surfing the internet is like leaving breadcrumbs along a forest path. Except no birds ever fly in to clean it up. It's a long messy trail providing all kinds of clues to anyone inclined to look.
Christian Rudder has just that kind of inclination. He's co-founder and President of OK Cupid - an online dating site. He's just written a book called Dataclysm - Who We Are When We think No One's Looking.
Christian Rudder was in our Toronto studio.
What do you think? Is all this aggregate data contributing to a more democratic view of history? Or are you worried about all that information being collected about you?
