It doesn't really matter what type of ranking system is used. It's the people using it. I visit another site that currently uses a 1-10 ranking and they were discussing changing to R'osity's method. People mostly give images a "10" over there. I think it's the same anywhere you go. I'm not a frequent poster, either in a forum or on images I view, but when I do decide to post on someone's pic, I try to politely point out what looks wrong to me. I try to avoid subjective issues, like "that ship would be better with more guns" since I know the artist may very well have WANTED it that way. But it seems to me that any ranking system is only as flawed as the people using it. This is not to say that everyone abuses it, but certainly quite a few do, or topics like this wouldn't keep appearing here and other places.
