Actually from a standpoint of diagramming human intellectual output, both reddit and YC do poorly. Even so, I can't think of any simple mathematical processes that would be better. Systems dealing with human beings must take into account intangibles and not attempt to reduce human beings to machines. This is the fundamental flaw of the Turing project.
