I'm with Steve and Marc with this, to a point. Yes a good photo is one that I wish I could have taken myself, but a great photo is one that I makes me wonder how it was taken so that I learn from it. I think the difference is subtle. It all it took for a photo to be good was that I had the skill to have taken it, then I fear that my judgement of a good photograph may be a bit solopsistic. But to a degree, that is what taste involves. Sometimes what makes a great photo is realizing just how obvious the photograph should be (in terms of subject matter, etc.), but that I didn't see it. All in all, I think that what I'm trying to say is a good photo should grasp my attention and keep it focused.
