IEEE Spectrum: How Much Information Was Consumed By Americans In 2008?

What the GIIC researchers found (or better estimated), was that in 2008 the average American consumed 100,500 words and 34 gigabytes of information for 11.8 hours on an average day. In 1980, Americans averaged 7.4 hours consuming information.
"Information" is defined as flows of data delivered to people and is measured in the bytes, words, and hours of consumer information. Video sources (moving pictures) dominate bytes of information (television mostly), with radio not that far behind.
 
However, the study notes that, "computers have had major effects on some aspects of information consumption. In the past, information consumption was overwhelmingly passive, with telephone being the only interactive medium. Thanks to computers, a full third of words and more than half of bytes are now received interactively. Reading, which was in decline due to the growth of television, tripled from 1980 to 2008, because it is the overwhelmingly preferred way to receive words on the Internet."

5 Impressive Real-Life Google Wave Use Cases

"Should you happen to be one of those people, we’ve got a number of different resources that you can use to get up to speed with Google Wave. This time around, however, we wanted to look at how people are actually using it now. From process modelling and customer service, to project collaboration, annotation, and gaming, the examples listed here highlight the power of the newborn medium, and in part, showcase what we can expect as the platform matures."

Global Warming - Salon.com

"So what's next? A series of essays by Sarah Palin about the Large Hadron Collider and the mysteries of dark matter? An MIT lecture series by Rush Limbaugh regarding the thermodynamics of black holes? A Festschrift of Sean Hannity's scholarly articles on plate tectonics and volcano formation? Glenn Beck performing live heart-lung transplants on Fox News?

Everybody understands that these things couldn't happen. That when it comes to serious scientific endeavor, years of study and professional apprenticeship are required. In a word, expertise.

Ex-beauty contestants, drive-time DJs, TV sports announcers, hairstylists, newspaper columnists -- basically anybody whose math skills topped out in the 10th grade -- rarely have anything substantive to add to the sum of technical and scientific knowledge. That's what they most resent about it.

It's not impossible that such persons could educate themselves sufficiently to have an informed opinion, but it's rare. Most of us, most of the time, are like historian and blogger Josh Marshall: "The fact that the vast majority of people with specialized knowledge in the field think there's a problem is good enough for me," he wrote. "I can't be knowledgeable about everything. And I'm comfortable with the modern system in which the opinions of really knowledgeable people with expertise counts more in cases like this than people who know nothing at all.""
