DIY has become pervasive in our culture. In part it is fueled by the internet, most particularly by YouTube. In part it is energized by time and money savings. It is further driven by the possibility of personalization and customization to meet individual needs just in time and just in place. More than 50 percent of the DIY-ers are between 24 and 44 years of age, and the numbers are growing. This trend is immutable now; it is continuing to grow in numbers and expand into new fields every year. Perhaps we have not been losing learners in the U.S. at all. In fact, there may be millions more postsecondary learners in the U.S. than ever before; they are simply not enrolling directly in colleges and universities, but instead choosing to DIY via MOOCs and other online, nondegree modes.
