I don't know why some boards are more popular than others. IMO the biggest annoyance here is the repetition, but I don't know how to fix it. In general, I don't think members should be banned simply for being loudmouths. I'm glad Rob is allowed to express himself here, and I know the ignore feature is available if I need it. (So far, I haven't ignored anyone.)
Some topics are doomed from the start. The proper analytical tools for this situation are mathematics and/or simulations. Actually playing the game is at best a complete waste of time, so the math-oriented posters tend to give lazy or sarcastic responses, although the correct answers are probably mixed in to the discussion.
