Speaking for myself only, I can't offer a solid critique if I'm left guessing as to the photographers intent. More often than not photos are posted here with no context and no hint toward what the photographer was trying to capture. So unless the story or intent of the image is easy to figure out, I'm left without a basis on which to judge whether or not the image was successful. Those looking for critique really need to be explicit as to what the photographer wants the viewer to see and understand. Otherwise it's just a guess as to what the meaning of the image is.
