Mark:
I think I agree with your overall point, which I read to be that you would like to see more substantive conversation on courses. The Whip it Out and Top Ten (admittedly started by me) threads may have had an original point that has since gone by the wayside, and now only seem to serve as what one poster once described as a self-administered pat on the back.
I generally like the photo tours, but I do agree with your point that they are better when combined with analysis. I have to ask though, does the onus fall on the tour guide to provide the analysis, or should that responsibility lie with all of us? As an example, Kyle Henderson has been dutifully plugging through a tour of Whistling Straits, a course that should be worthy of a great deal of conversation and perhaps quite a few differing opinions. Yet the participation in that thread has been muted.
If anything, I would have to disagree with Pat Craig. The clutter may be down, but the general quality of the discussion is not up to par with the early days.
