I think the distinction is not in length, but in content and articulation. It also has a lot to do with how things are said. If you just explain things as you would in any expository essay, then likely we're not going to get much from it. People can explain how much they love _____ until they're blue in the face, but if they don't infuse their personality into the equation, then I won't be able to get anything from it for sorting. Sorting is harder than it seems sometimes, haha. XD
