One irony about the proliferation of blind shots at NGLA--which I've only walked (during the 2013 Walker Cup), not played--is that in replicating at NGLA perhaps the most famous UK hole (North Berwick's Redan), Macdonald actually eliminated the blindness.
I agree with John, especially his first point. Blind shots are, to me, the most compelling in golf. Some might prefer long (especially water) carries on par-3s (think the 16th at Cypress or the 9th at Yale), but the suspense of those shots--seeing the ball in the air, trying to determine where it will land--is prolonged with blindness. You get to see the ball in the air, but you have no idea where it landed or, more to the point, ended up--until you walk over the hazard (typically a ridge or other landform) that's responsible for the blindness. Because the anticipation is always compelling, the moment of discovery--be it fortuitous or not--is always experienced acutely.
