David Pogue:

Things don't replace things; they just splinter.

We want it easy.

Everybody reads with a lens.

The trick is to accept your gadget's obsolescence at the time you buy it.

Michael Becker of the Mobile Marketing Association:

In the world of mobile, there is no anonymity.

Julia Angwin And Jennifer Valentino-Devries:

Advertisers no longer want to just buy ads. They want to buy access to specific people.

Ann Blair:

A new technology does not act alone, after all, but in concert with our ambitions for it. Overload has long been fueled by our own enthusiasm -- the enthusiasm for accumulating and sharing knowledge and information, and also for experimenting with new forms of organizing and presenting it.

Early modern compilers were driven by this enthusiasm, even beyond their hopes for acquiring reputation or financial gain. Today, we see the same impulse in the proliferation of cooperative information sharing on the Internet, such as the many designers and programmers sharing new ways to visualize and efficiently use huge quantities of data. In democratizing our ability to contribute to a universal encyclopedia of experience and information, the Internet has shown just how widespread that long-running ambition remains today.

An exchange with Tom Scocca and Eliza:

TS: My primitive little heart is troubled, Eliza.

Eliza: Why do you say your primitive little heart is troubled eliza?

TS: I have been reading Twitter.

Eliza: Can you elaborate on that?

TS: On Twitter, I am having a hard time telling the bots from the humans.

Eliza: How long have you been having a hard time telling the bots from the humans?

TS: Weeks and weeks now.

Eliza: Please go on.

TS: It is not because the bots are fluent or facile.

Jeffrey Rosen:

Facebook has more power in determining who can speak and who can be heard around the globe than any Supreme Court justice, any king or any president.

Steve Steklow and Paul Sonne:

"If I come online and I'm in work mode, I will show up as a very different character than when I go online Saturday morning and I'm in recreation mode," says Mike Gassewitz. The targeted ads would reflect which "character" is online.
