That’s not to say there isn’t any room for humans in Demand’s process. They just aren’t worth very much. First, a crowdsourced team of freelance “title proofers” turn the algorithm’s often awkward or nonsensical phrases into something people will understand: “How to make a church-pew breakfast nook,” for example, becomes “How to make a breakfast nook out of a church pew.” Approved headlines get fed into a password-protected section of Demand’s Web site called Demand Studios, where any Demand freelancer can see what jobs are available. It’s the online equivalent of day laborers waiting in front of Home Depot. Writers can typically select 10 articles at a time; videographers can hoard 40. Nearly every freelancer scrambles to load their assignment queue with titles they can produce quickly and with the least amount of effort — because pay for individual stories is so lousy, only a high-speed, high-volume approach will work. The average writer earns $15 per article for pieces that top out at a few hundred words, and the average filmmaker about $20 per clip, paid weekly via PayPal. Demand also offers revenue sharing on some articles, though it can take months to reach even $15 in such payments. Other freelancers sign up for the chance to copyedit ($2.50 an article), fact-check ($1 an article), approve the quality of a film (25 to 50 cents a video), transcribe ($1 to $2 per video), or offer up their expertise to be quoted or filmed (free). Title proofers get 8 cents a headline. Coming soon: photographers and photo editors. So far, the company has paid out more than $17 million to Demand Studios workers; if the enterprise reaches Rosenblatt’s goal of producing 1 million pieces of content a month, the payouts could easily hit $200 million a year, less than a third of what The New York Times shells out in wages and benefits to produce its roughly 5,000 articles a month.

But once it was automated, every algorithm-generated piece of content produced 4.9 times the revenue of the human-created ideas. So Rosenblatt got rid of the editors. Suddenly, profit on each piece was 20 to 25 times what it had been. It turned out that gut instinct and experience were less effective at predicting what readers and viewers wanted — and worse for the company — than a formula.

Here is the thing that Rosenblatt has since discovered: Online content is not worth very much. This may be a truism, but Rosenblatt has the hard, mathematical proof. It’s right there in black and white, in the Demand Media database — the lifetime value of every story, algorithmically derived, and very, very small. Most media companies are trying hard to increase those numbers, to boost the value of their online content until it matches the amount of money it costs to produce. But Rosenblatt thinks they have it exactly backward. Instead of trying to raise the market value of online content to match the cost of producing it — perhaps an impossible proposition — the secret is to cut costs until they match the market value.

I’ve been to parties and social gatherings there many times where one set of people stay at one end of the room and another -- the newcomers -- at the other end.

Gentrification in Berlin has now started to make itself felt in staunchly working class and immigrant Neukoelln

A video has recently appeared on YouTube about the phenomena of gentrification in Neukoelln

can understand some of the points he makes about the superficiality of the hipsters with their “Starbucks standards and expectations” and how they just want to party for a few years before moving on again somewhere else. But I don’t entirely agree with his point of view. Berlin needs newcomers, it needs new creativity and new enterprise. It can’t afford to stagnate and just remain a working class city in a city with little for the working class to do anymore. I find this hostility towards “Aerzte, Architekten und Anwaelte” rather parochial and narrow-minded. Why be against these people? Because they are doing well for themselves? What are they supposed to do? Sweep the streets or draw Stuetze (unemployment benefit)?

funny rant, critical of the newcomers and their standardized Latte Macchiato attitudes.  The video was also featured on Dutch TV recently.

Edmodo has finally created a quiz application!

Edmodo’s quiz feature allows you to create a quiz that mixes multiple choice, short answer, true/false, and fill in the blank.

But like QuizStar, Edmodo also analyzes results for you.

Rules for ALL Online Quizzes 1.  Never, ever, EVER copy a question from a textbook or a quiz you found online. I can almost guarantee that some enterprising student somewhere has copied the question and placed an answer key online.

Getting the Most out of Formative Assessments 1.  Set a time limit that will simultaneously allow students enough time to an

Getting the Most out of Open Note Formal Assessments 1.  If you are going to permit students to use notes and worksheets from class, design your questions so that they must apply the information they have at their fingertips. I

Getting the Most out of Closed Note Formal Assessments 1.  If no notes are permitted, reduce the amount of time students have to take the test. For multiple choice at the high school level, 45 seconds per question is fairly standard.

Experimentation and Feedback As you play around with online quizzes, ask your students to give you feedback. They’ll let you know what’s working and what isn’t.
