Jonathan, in my understanding that is related to the follow-your-nose principle. If I see a URI for a, say, predicate, I may want to follow that URI and get some information. That predicate (or class or whatever) is rarely alone, it may be part of a vocabulary. If the URI is of the form http://blabla#blah, that means that I, typically, have a large vocabulary file at http://blabla and #blah is somewhere there. So if I dereference http://blabla#blah, I will get the full vocabulary and I will have to locate the specific element #blah to something with it (as a caller). If the vocabulary is very large, that might be a pain. If the URI is of the form http://blabla/blah, and I dereference it then I can expect to get only the information I am looking for. There may be other reasons; that is the one which resonates with me, personally...
