as Viktor Mayer-Schönberger argues convincingly in his book Delete: The Virtue of Forgetting in the Digital Age (Princeton University Press, 2009), the costs of such powerful collective memory are often higher than we assume.

"Total recall" renders context, time, and distance irrelevant. Something that happened 40 years ago—whether youthful or scholarly indiscretion—still matters and can come back to harm us as if it had happened yesterday.

an important "third wave" of work about the digital environment. In the late 1990s and early 2000s, we saw books like Nicholas Negroponte's Being Digital (Knopf, 1995) and Howard Rhein-gold's The Virtual Community: Homesteading on the Electronic Frontier (Addison-Wesley, 1993) and Smart Mobs: The Next Social Revolution (Perseus, 2002), which idealistically described the transformative powers of digital networks. Then we saw shallow blowback, exemplified by Susan Jacoby's The Age of American Unreason (Pantheon, 2008).

Her prediction: Companies will soon sell robots designed to baby-sit children, replace workers in nursing homes, and serve as companions for people with disabilities. All of which to Turkle is demeaning, "transgressive," and damaging to our collective sense of humanity. It's not that she's against robots as helpers—building cars, vacuuming floors, and helping to bathe the sick are one thing. She's concerned about robots that want to be buddies, implicitly promising an emotional connection they can never deliver.

y: We are already cyborgs, reliant on digital devices in ways that many of us could not have imagined just a few years ago

"We are hard-wired that if something meets extremely primitive standards, either eye contact or recognition or very primitive mutual signaling, to accept it as an Other because as animals that's how we're hard-wired—to recognize other creatures out there."

Pete said “everybody blogs” in the same tone of voice that people use when they refer to the children’s book Everybody Poops, thereby making blogging seem as if it’s just as thoughtful and intellectual of an activity as the subject of that children’s classic.

the blogs I read regularly have far more to offer. Some I read for information, some to get me thinking about a topic and to inform me what others have already thought, some to amuse me, some to delight me, some to make me angry, and some because I am trying to find yet another way to distract me from finishing those introductions

The Man Who Lied to His Laptop condenses for a popular audience an argument that Nass has been making for at least 15 years: humans do not differentiate between computers and people in their social interactions.

At first blush, this sounds absurd. Everyone knows that it's "just a computer," and of course computers don't have feelings. And yet. Nass has a slew of amusing stories—and, crucially, studies based on those stories—indicating that, no matter what "everyone knows," people act as if the computer secretly cares. For example: In one study, users reviewed a software package, either on the same computer they'd used it on, or on a different computer. Consistently, participants gave the software better ratings when they reviewed in on the same computer—as if they didn't want the computer to feel bad. What's more, Nass notes, "every one of the participants insisted that she or he would never bother being polite to a computer" (7).

Nass found that users given completely random praise by a computer program liked it more than the same program without praise, even though they knew in advance the praise was meaningless. In fact, they liked it as much as the same program, if they were told the praise was accurate. (In other words, flattery was as well received as praise, and both were preferred to no positive comments.) Again, when questioned about the results, users angrily denied any difference at all in their reactions.

Rating Characteristics 4 Exceptional. The blog post is focused and coherently integrates examples with explanations or analysis. The post demonstrates awareness of its own limitations or implications, and it considers multiple perspectives when appropriate. The entry reflects in-depth engagement with the topic. 3 Satisfactory. The blog post is reasonably focused, and explanations or analysis are mostly based on examples or other evidence. Fewer connections are made between ideas, and though new insights are offered, they are not fully developed. The post reflects moderate engagement with the topic. 2 Underdeveloped. The blog post is mostly description or summary, without consideration of alternative perspectives, and few connections are made between ideas. The post reflects passing engagement with the topic. 1 Limited. The blog post is unfocused, or simply rehashes previous comments, and displays no evidence of student engagement with the topic. 0 No Credit. The blog post is missing or consists of one or two disconnected sentences.

today’s students struggle with a feeling of information overload. “They feel overwhelmed, and they’re developing a strategy for not drowning in all information out there,” she said. “They’re basically taking how they learned to research in high school with them to college, since it’s worked for them in the past.”

college students approach research as a hunt for the right answer instead of a process of evaluating different arguments and coming up with their own interpretation.

Students at Northern Arizona University who hope to skip large lecture courses may have more trouble doing so this fall: The university is installing an electronic system that measures student attendance. The university is using $75,000 in federal stimulus money to install the system, which will detect the ID cards students are carrying as they enter large classrooms. (The cards can be read by an electronic sensor.) Faculty members can choose to receive electronic attendance reports.

the Facebook group "NAU Against Proximity Cards," which has over 1,300 members.

In light of last week's vote by its legislature, I think the Arizona schools should go a step further and require passports and birth certificates to enter classrooms.

Caprica may have gone too far, tried to cover too much. It broke one of the cardinal rules of mainstream science fiction, which is that if you have a strange alternate universe you'd better populate it with recognizable, ordinary characters. But I like the kind of thought-experiment audaciousness that says, Hell yes we are going to give you complicated characters who defy stereotypes, and put them in a world whose rules you'll have to think hard to understand. It's too late to bring Caprica back. But I hope that this show is the first part of a new wave of science fiction on TV. Like The Sarah Connor Chronicles, Dollhouse, and Fringe, Caprica tackles singularity-level technology as a political and economic phenomenon - not as an escapist fantasy. And that's why it was a show worth watching, even when it stumbled.
