itwbennett writes: A new IDC study has found that 'of the 18.5 million software developers in the world, about 7.5 million — roughly 40 percent — are so-called hobbyist developers, which by IDC's definition is 'someone who spends 10 hours a month or more writing computer or mobile device programs, even though they are not paid primarily to be a programmer.' Lumped into this group are students, people hoping to strike it rich with mobile apps, and people who code on the job but aren't counted among the developer ranks. Link to Original Source
