Melvyn,
I have played a lot of blind holes, and I enjoy them when they fit my criteria above just fine. As an architect and golfer, I hate them when I know or sense that the architect just didn't try hard enough. One gca actually told me he was fine if his courses had a few bad (not just blind) holes, because he didn't work hard enough to avoid them.
I don't care for them conceptually as an architect for a lot of reasons. First, I was taught that way, and despite all the calls for them here, I still think to avoid blind holes via routing, features, etc. Second, as an LA, I dislike the thought of creating landscape beauty and then hiding it, although the slow reveal is occaisionally great, too. Maybe more suited to the "sense of entry" into a golf corridor.
There are saftey problems, of course, and most golfers just don't like them. And, most owners hate to pay for expensive sand bunkers just to hide them from full view!
As a golfer, I sure don't feel cheated, either. While I enjoy a variety of hole concepts, not having any one particular one on a golf course, including blind shots sure doesn't distract from my day!
