Enjoy a sampling of the stories from around the internet that captured our interest this week:

• This look at the dramatic rise of MOOCs and other online college offerings points out a basic conundrum: can these courses make money? [The New York Times] Several TED speakers have given talks about online education this year: Peter Norvig described his 100,000 student classroom, Daphne Koller showed how Coursera is collecting data, and Shimon Schocken explained his self-organizing computer course. None of them see making money as a motivator. Should knowledge be a commodity?

• Vietnam, which is not known for its liberal civil rights policies, is considering a same sex marriage bill, which would make it the first Asian country to do so. Love this photo collection on LGBT life in Vietnam.  [The New York Times, Lens]

• Suzanne Moore’s piece in New Statesman is such a good rant and had us thinking for days. However, there has been backlash to the piece, focused on a point Moore was trying to make about female body image; in a sad exercise, the backlash turned into internet abuse, until Moore left Twitter. [Pink News]
