Most universities are not teaching about social media.

Over the next few slides we've rounded up 12 excellent free and open source applications worth investigating and experimenting with.

"Blazek's response to an e-mail and LinkedIn request from Diana Mekota, a 26-year-old planning to move to Cleveland this summer, has made the rounds on Reddit, Buzzfeed and other viral hotspots after Mekota posted it to her Imgur account. And the resulting backlash is yet another cautionary tale about how posting something mean-spirited online can come back to haunt you in the social media age."

""We're going to transfer power without any kind of wires," says Dr Hall, now Chief Technology Officer at WiTricity -- a start-up developing wireless "resonance" Technology. "But, we're not actually putting electricity in the air. What we're doing is putting a magnetic field in the air.""

""Where's the beef?" was the famous campaign slogan from the 1984 Presidential campaign. For two years, MOOC watchers have been asking the same question, as hundreds of thousands of students participated in free online courses that delivered knowledge but no certification of any real value. The Georgia Institute of Technology recently changed all that: Its May 14 announcement that the school would offer a fully accredited Online Masters of Science in Computer Science (OMS CS) for less than $7,000 suddenly brought the abstract potential of MOOCs into stark relief."

"A quick search for "edtech communities" returns thousands of results. Here's a helpful list of some of the best communities for professors, administrators and IT workers. "

"Kno, in many ways is a case study in Silicon Valley hubris, where white-boarding and theoretical thinking doesn't always match up with the reality of the real world. A book publishing industry insider pointed out that Kno was trying to solve a problem that wasn't acute enough for the publishers and the end customers - students. It was a problem Kno wanted to solve for Kno."

"Teens are cooling on Facebook, a trend suggested by recent research and acknowledged, this week by Facebook itself. The shift was confirmed time and time again in e-mail and phone interviews with dozens of teens and their parents in CNN's reporting of this story. While the social-networking juggernaut continues to chug along among adults, boasting more than 1 billion active users, younger users are flocking to newer, and arguably hipper, networking tools."

"Students are heading back to campus. And when they finish writing that first paper of the year, a growing number will have to do something their parents never did: run their work through anti-plagiarism software. One company behind it is called Turnitin. And the database it uses to screen for potential plagiarism is big. Really, really big."

"Only after the post gets a certain number of likes and shares does the scammer edit it and add something malicious. In fact, if you go back through your history of liked posts, you might find that some of them have changed to something you wouldn't have liked in a million years."
