How important is Twitter in the political revolutions sweeping the Middle East? That was the topic of discussion on stage at the CTIA mobile and wireless convention today in Orlando, Florida and two very different, very strong opinions were voiced. "I don't think anyone in their right mind would say that sending a tweet is the equivalent of activism," said Twitter co-founder Biz Stone, "but it's another tool people can use." Kenneth Roth, executive director of of Human Rights Watch, one of the world's most respected human rights organization, framed things very differently though. He said on stage (above) that mobile technology in general would make it impossible today for something like Nazi Germany to unfold again the way it did historically.

We like to think the human brain is special, something different from other brains and information processing systems, but a Cambridge professor is set to test that assumption - by conducting a live experiment using Twitter.

Not all research papers receive their own hashtag on Twitter. But #arseniclife (as it was dubbed in tweets) was no ordinary paper.

The terse announcement came just after 9:45 p.m. Sunday from Dan Pfeiffer, the White House communications director. "POTUS to address the nation tonight at 10:30 PM Eastern Time," he wrote on Twitter, sharing the same message that had just been transmitted to the White House press corps. According to Brian Williams, the "NBC Nightly News" anchor, some journalists received a three-word e-mail that simply read, "Get to work.

A survey by the National Association of Realtors conducted in March 2011 revealed that 62 percent of people ages 18-29 said they would prefer to live in a communities with a mix of single family homes, condos and apartments, nearby retail shops, restaurants, cafes and bars, as well as workplaces, libraries, and schools served by public transportation.  A separate 2011 Urban Land Institute survey found that nearly two-thirds of 18 to 32-year-olds polled preferred to live in walkable communities. Younger Americans are also using technology to substitute for driving, connecting with friends and family online, substituting Facebook, Twitter, Skype, or FaceTime interactions for in-person visits and using online shopping and e-commerce in place of driving to and from grocery and retail stores, the report notes. For generations of Americans, car ownership was an almost mandatory rite of passage-a symbol of freedom and independence. For more and more young people today, a car is a burden they no longer wish to carry. 

The living room is the epicenter of family, the hub of the household. Perhaps more so than the dining table, the living room hosts hours upon hours of family attention and interaction every week. Whether we were gripped by the music and voices emitting from radios or entranced by the moving images illuminating our televisions, we celebrated everything from togetherness to relaxation around a common centerpiece. This once mighty magnet of attention, through its iterative forms, is learning to share its powers of attraction forever changing the idea of the family cornerstone. Now attention is a battlefield and the laws of attraction are distributed.

As I read both Carr and Shirky over the past couple weeks-who both seek parallels between the rise of the internet and digital social media and the invention of the printing press in the 16th century-I couldn't help thinking about medieval manuscripts. Since the early 1990s, both medievalists and electronic media theorists have pointed to the hypertexted quality of medieval illuminated manuscripts in making complementary claims: medievalists to continuing cultural relevancy and electronic media theorists in continuity to literary tradition. The medieval books we admire so much today are distinguished by the remarkable visual images, in the body of a text and in the margins, that scholars have frequently compared to hypertexted images on internet "pages."

A full hour before the formal announcement of Bin-Laden's death, Keith Urbahn posted his speculation on the emergency presidential address. Little did he know that this Tweet would trigger an avalanche of reactions, Retweets and conversations that would beat mainstream media as well as the White House announcement. Keith Urbahn wasn't the first to speculate Bin Laden's death, but he was the one who gained the most trust from the network. Why did this happen?
