Facebook and Twitter are in a heated fight to own the Web's town square, because becoming the go-to hub for real-time events like television shows could draw more user activity and more advertising dollars. A key piece in winning this battle is data -- proving to networks and advertisers that the activity on their service is meaningful.

Marco Arment:

Many people with iPhones and iPads full of apps have never bought a single paid-up-front one.

Paul Ford:

A few months ago there was a good bit of speculation as to who owns your [digital] music after you die, and the answer was: "no one you know."

Rick Smolan:

A gentleman has a pacemaker; it's a wireless pacemaker, so throughout his day the data from his heart is transmitted to his doctor, and he actually spent time looking at his exercise, his nutrition, his alcohol consumption, and he wanted to find out whether there is some correlation between his other activities and when his pacemaker kicked in. So he called the manufacturer saying, "Could I get a copy of the last six months of my heart data?" and they said, "Sorry, sir, this is proprietary." He said, "Wait a second. This is my heart. You have been collecting information about my heart; I want a copy of the information." They have refused to give it to him.

Daniel Castro, a senior analyst at the Information Technology and Innovation Foundation:

Countries are competing to be the Cayman Islands of data privacy.

Matthew Buchanan:

We need to regulate how public data is used, not whether it's available.

Noam Cohen's friend:

Privacy is serious. It is serious the moment the data gets collected, not the moment it is released.
