The best things in life are free. And that's the problem here. Knowledge sharing, MOOC's (massive open online courses) and open source education is awesome and gives accessibility to the best information in the world. When you have a lot of knowledge, it becomes a commodity--and a precious commodity should have a high price tag, right?But knowledge really is priceless, and like paying for love, when you pay for knowledge, you might not get what you pay. And like paying for love, sometimes pimps want to control the market. And is that necessarily wrong? Because to make knowledge profitable means to make it sustainably accessible. A friend of mine (@habib) is a product manager at Elsevier and I wonder what he thinks about this. He happens to have been recruited by the company years ago from his blog on library science, and now he works on finding up-and-coming knowledge innovations. I'm going to tweet this to him and see what he thinks.
