For the mathematically-inclined, (or at least those not frightened off by! ) if you have a fairly active forum, and want to start getting a better sense for which concepts / topics are discussed more and less often across threads, you can use this sort of analysis to help surface these, for use for further product development, customer acquisition, etc.
