Hindsight is always 20/20, they say. Unless, of course, you spend most of your time navel gazing. So it’s almost myopic to point out that some ideas’ time has come. And other ideas’ time has passed. On one hand, it’s time for every sale to include in-house ancillary sales. On the other hand, it’s time for NAR to give up the dream of one HAL-like central database. Didn’t they find the bellybutton lint the last time they tried it?
