Ok, so I understand that we don't want to have critiques in PSE. I think I can even get my head around why. ;-)
Nevertheless, I'd still love to tap into this community (and this software) to do critiques. The other options out there either have lousy software or dysfunctional user communities. I really like the self-managing capabilities of this site, and the people here have been really impressive. I keep thinking that these raw materials could yield a really awesome critique site, too.
I know that a big issue is the non-definitive nature of the answers in critiques, but I don't think this is a showstopper. There are clearly questions on our site right now for which the answers are subjective. I know that the idea of accepting the "best" critique might not seem to make sense, but we see the analog all the time here -- a well-worded, well-explained answer will almost always be voted higher than an equivalent answer that's terse or cryptic. I don't see this as a showstopper, either.
So, is there any way to run this up the flagpole? Would something like this need to be a whole new SE site? I mean, if we can do meta.photo.stackexchange.com, why not critique.photo.stackexchange.com?
