Great link! It's hard to improve on a photo when it simply "does nothing" for a viewer. Maybe these will help people better explain their opinions of a photograph.
On another note, why doesn't the forum have some sort of conduct for people posting photos for critique? We see so many threads started every day where a person just throws up a number of pictures and says "what do you think". It would be good etiquette for the person posting to explain the concept behind their photos, a brief explanation of the methods they used, what elements they feel are strong/weak, and anything else the viewer can relate to when providing a critique. It would be great practice for anyone trying to improve their photography to first critically analyze the photo themselves and then see what others think. Maybe then we wouldn't see so many threads started with random photos with no thought put into them. Or at least when a photo looks that way, we can know what the photographer was trying to achieve, and provide more sound advice for improving the photo.
Sorry to threadjack, and I know I haven't been a long time member here, but I feel this would greatly improve the quality of work and would help everyone develop a more critical eye in they way they view photographs.
