Well, I want to hear your personal views so sue me.
"But why do you have these opinions? what values does TD not meet such that it can't be seen as a way of doing art? You may end up at Nate's view eventually, but I'm trying to get past the bare opinions and get at comparisons and rationales for those opinions."
I've heard it described as factory work before, perhaps that turned me off. Made me think it was more like paint by numbers. Now, I've heard another TD developer talk about it in such a way that they described with loving detail and passion. I vibed on that. And someone can use the metaphor of art, and talk about a need for experience in the craft of TD, but it just doesn't move me - the TD equipping of the route. The climbing of it, hell yeah. Whereas the GU equipping of a route gets my attention.
I am interested in knowing how a climb is put up but don't spit on it and say phooey or anything however it was done. I have not infrequently enjoyed imagining what it was like on the FA of climbs if GU, and also not infrequently wondered if a climb was established GU when I wasn't sure.
Anyways, sure enjoying everyone's input.
One more thing tonight before I go to bed, I do like the notion of getting a good ass kicking trying to put up a route whether GU or TD. That sounds like where it's at to me... someone really trying to push their own limits.
