itwbennett writes "Eric Bloom, an IT leadership coach and former CIO, has answered that eternal question 'does working on old software hurt your professional marketability' with a somewhat surprising 'no.' But, Bloom adds, 'a techie's skill set from a marketability perspective has a two year half-life. That is to say, that the exact set of skills you have today will only be half as marketable two years from now.'"
