Jerry,
I'll only do a reverse slope on a green if there is enough room out front to bounce a ball in. I may reverse slope the Sunday pin location as long as some of the green is receptive, but I still think (and most good players do) that the majority of the green ought to recieve the shot.
I do see a trend of more reverse slope greens, and greens contoured so that only a shot to a 20' circle will hold without rolling off a false front, or whatever. I was always taught that a crowned green is terrible design, and yet I see more and more of them.
While I encourage all architects to experiment some of the time, and some architects to experiement all of the time, I think the basic premise of building fairly receptive greens still is valid, despite technology, etc. Think how hard that shot is for the rest of us if Greg Norman doesn't think its doable.
