Over the past day, Al Jazeera has pushed the issue with its promoted trend and tweets like this, which reads "Like our coverage from #Egypt? Think we should be shown on US TV? It's time to #DemandAlJazeera http://aje.me/demandAJ." Yesterday, clothing outlet Kenneth Cole tried to leverage the popularity of Egypt-related hashtags in a similar manner, tweeting "Millions are in uproar in #Cairo. Rumor is they heard our new spring collection is now available online at http://bit.ly/KCairo." Immediately, the company caught a lot of flack for the tweet and shortly after publicly apologized and pulled the tweet. The difference in the two situations, we would think, is that Al Jazeera is trying to leverage the popularity of a specific event to gain entry into a market that has essentially shut it out. The end result might be similar to Kenneth Coles' desired outcome - increased sales - but it would come with the increased spread of information.

"When you create a new article, blog post, or a new page on your web site (a new URL), the search engine will crawl that URL. They might even see some links form other web sites to that new URL. But if the search engines see real people mentioning the URL and interacting with it, they consider that the URL is validated, socially. The URL is "accepted". And it's that human interaction that the search engines are looking for. If the search engines can figure out some form of social validation of a URL, then most likely it is going to be a page that they will want to show in their search results. Social validation is that human SEO factor that the search engines have been looking to include in their algorithm for a very long time."

The best managers know how to frame work as a problem that is a lot of work to complete and a small amount of work to check. Mediocre managers spend too much time checking and revising their employees' work, and begin to approach the cost of just doing it themselves. (The worst managers hire incompetent people.) Wolfram Alpha made me this cute Venn diagram of the sweet spot: Competent (C) and not Micromanaged (M). Teams led by good managers reside in the shaded area of the diagram.

If you didn't hear, yesterday Charlie Sheen joined Twitter. Today he very well may reach 1 million followers (as I type he's already passed the 900K mark). How did it happen?  Why all of a sudden did he wake up and decide it's Twitter time? And how was it that Charlie Sheen went from non-twitterer to hardcore twitterer overnight?  Short answer: he got a lot of help from a team of experts at Ad.ly, a small Beverly Hills start-up that focuses on celebrity endorsements via Facebook and Twitter.

On Friday, I instigated a call to help a friend of mine in New Zealand. What I asked for was not money, and not much time, really; rather, I asked for people to record a short message (20 seconds max) in support of the people in Christchurch who have suffered so much from the earthquakes that have plagued their wonderful city. How this story is supposed to end is this: hundreds of thousands of people heard my plea for help, and overwhelmed my server with messages of hope. The number of messages and the outpouring of passion and love for this cause brought the Interwebs to its knees. The people of New Zealand clung to those messages of hope - and another social media legend was born. This did not happen.

"Our goal at Zappos is to inspire -- not motivate -- employees to treat each other like family. For example, most Zappos employees when they leave the office leave to hang out with other Zappos employees. That's behavior you can't force upon employees. They actually have to want to do it." "Many companies are focusing on the current quarter or current year at best. The good news is that information is moving faster and faster and companies are becoming more and more transparent whether they like it or not. As a result, the lag time between brand and culture is becoming less and less, so in the long run I think the 'good guys' will win."

I have always believed that collaboration is most meaningful when you are really creating something together and when you are sharing your thoughts before they are finished products. If I am only willing to show you something that is a polished document, you might edit or change it a little, but you are not really doing it with me. People have to trust each other to do that. It is risky to show people your unfinished thoughts. Technologies for a long time could let you do that; people did not always do that. Social software, to the extent that it is helping people build trust and be comfortable with more casual, lightweight communications, could make it possible for more of our attempts at collaboration to be real collaboration.

The Army has a well-established history of using television commercials to reach possible recruits. The Times quotes the simply impossibly named Lt. Gen. Benjamin C. Freakley on the motivation for the new direction in recruiting. "We're working hard to increase our social media. We fully recognize that young people TiVo over commercials or are multitasking on their smartphones when the commercials come on...We have to reach out in forms like we're discussing to get them to want to know more, to join us in social media and extend the dialog." The branding message remains consistent, if not terribly clear to me: "Army Strong." It plays out across a number of properties, including a website, Army Strong Stories, and a Go Army Facebook page (complete with exclusive X-Men movie footage).

Businesses that hoard information in their head office and keep staff in the dark on important metrics risk falling behind their competitors, according to MIT business guru Jeanne Ross. For organisations to fully benefit from this information, they need to share it with their staff, customers and business partners, she said. Once these groups get hold of such information, they can use it to take decisions that will boost the business. Customer service reps with a raft of data are more likely to be able to answer customer queries without having to refer the customer on, for example, and in the process save the company both time and money. But instead of spreading this information around, businesses have a tendency to keep it in head office and share it between a small pool of managers, who use it to run the business from the centre.

Next time you feel like broadcasting some gloomy tale of woe on Facebook, you might want to think twice. Your friends could catch your feelings. Psychologists have long known that emotions, just like germs, are contagious. People exposed to a person experiencing strong emotions may experience similar feelings, catching them through facial expressions, tones of voice or some other means. But now there is a new means of transmission -- social media. Facebook data scientist Adam D.I. Kramer analyzed postings by about 1 million English speakers and their roughly 150 million friends in multiple countries on the social network to show that the words people use in their status updates drive the emotions of their online friends, even days later. Kramer found people who used emotionally loaded words like "happy," "hug," "sick," and "vile" in their status updates sparked similar emotions in later Facebook postings by their friends.

According to new statistics from analytics firm Flurry, the average mobile user now spends 9% more time using mobile apps than the Internet. That's 81 minutes per day for mobile apps versus 74 minutes per day spent surfing the Web (both desktop and mobile). But mobile apps haven't always been more popular than the Web, says Flurry. Only last year, these positions were reversed, with users spending 43 minutes on apps versus 64 minutes on the Web.

In 2006, sociologists from the University of Arizona and Duke University sent out another distress signal-a study titled "Social Isolation in America." In comparing the 1985 and 2004 responses to the General Social Survey, used to assess attitudes in the United States, they found that the average American's support system-or the people he or she discussed important matters with-had shrunk by one-third and consisted primarily of family. This time, the Internet and cellphones were allegedly to blame. Keith Hampton, a sociologist at the University of Pennsylvania, is starting to poke holes in this theory that technology has weakened our relationships. Partnered with the Pew Research Center's Internet & American Life Project, he turned his gaze, most recently, to users of social networking sites like Facebook, Twitter and LinkedIn. "There has been a great deal of speculation about the impact of social networking site use on people's social lives, and much of it has centered on the possibility that these sites are hurting users' relationships and pushing them away from participating in the world," Hampton said in a recent press release. He surveyed 2,255 American adults this past fall and published his results in a study last month. "We've found the exact opposite-that people who use sites like Facebook actually have more close relationships and are more likely to be involved in civic and political activities."

The mass media, including interactive social-networking tools, make you passive, can sap your initiative, leave you content to watch the spectacle of life from your couch or smartphone. Enlarge This Image Apparently even during a revolution. That is the provocative thesis of a new paper by Navid Hassanpour, a political science graduate student at Yale, titled "Media Disruption Exacerbates Revolutionary Unrest." Using complex calculations and vectors representing decision-making by potential protesters, Mr. Hassanpour, who already has a Ph.D. in electrical engineering from Stanford, studied the recent uprising in Egypt. His question was, how smart was the decision by the government of President Hosni Mubarak to completely shut down the Internet and cellphone service on Jan. 28, in the middle of the crucial protests in Tahrir Square?

The time it takes for new products to come to market is getting ever shorter. As a consequence, goods are being produced using manufacturing facilities and IT systems that were designed with completely different models in mind. Fraunhofer developers want to make factories smarter so they can react to changes of their own accord.

For the first time, more college students are using smart phones than traditional feature phones, reports a new study from Ball State University.

For most people I meet, the phrase "social media" evokes post-2004 web technologies: Facebook, Flickr, Twitter, Foursquare, … (The phrase came into widespread use around this time.) But since its earliest days, the internet has been a very social place.

I've been capturing the Twitter Public Timeline since late 2009.  I have now nearly 6 million records, each one containing the message, of course, but also the name of the user and their "Followers" and "Following" count at that point in time.  I started doing scatter plots of this data and was amazed at the detailed structure evident in the data, that illustrate some interesting ways in which Twitter is being used.  No single graph can show it all, so I'm giving you a series of charts, each one showing an area of the Following/Followers phase space 10ox larger.

After Local Motors won the XC2V competition, they were given a mere 14 weeks to build a prototype of their "FLYPMODE" concept, a vehicle built on a common chassis capable of performing both combat resupply and medical evacuation missions. As it turns out, they didn't even need all 14 weeks, and were able to complete the prototype ahead of schedule, no problem. Check out a bunch of pics of the not yet armed but otherwise fully operational XC2V vehicle in the gallery below. Part of the point of this whole exercise was to see how effectively crowd-sourcing through private industry could be used to design, develop, and build a new vehicle. In a result that will shock nobody at all, the XC2V went from concept to prototype some five times faster than it normally takes our ponderously bloated war machine to come up with something similar. While DARPA hasn't commented on cost, I imagine that it was exponentially cheaper, too.

Social software helped TEVA Pharmaceuticals shrink its manufacturing cycle time by 40% between January and April -- when the company's Oracle ERP apps couldn't keep up with unpredictable market conditions.

If you file your emails into folders in your email program you're wasting your time, according to a study by IBM Research. The 345-user study found that people who used the search function in their email program could find relevant emails as easily as those who had categorised each email into folders. Finding emails by searches took on average 17 seconds, versus 58 seconds finding the emails by folder. The likelihood of success - that is, finding the intended email - was no greater when it had been filed in a folder. "People who create complex folders indeed rely on these for retrieval, but these preparatory behaviours are inefficient and do not improve retrieval success. In contrast, both search and threading promote more effective finding," the study said.
