Is there demand for a discussion site that has nothing to do with blog or news posts? Comments and threads could still be monitored and ranked by users. Discussions could be split into topics and subtopics (philosophy might be interesting, because some of the arguments would concern where to make the splits). The hard thing would be to make sure people voted up and down for the right reasons.
