I appreciate that the members are discussing this, and thinking about how discourse could be improved. Here is what I have noticed recently that I would like people to consider.
When posters engage in discussions on investing, there is predominantly at least the appearance of an effort to apply critical thought. When posters engage in discussions on politics, there is predominantly the appearance of regurgitating common beliefs. Very shallow. Even at least one thread I saw which revealed a lack of basic knowledge of civic functions/laws/powers.
Now it is easy enough for me to simply not click any thread that is non-financial, but here is the issue. People who think sloppily on one topic tend to think sloppily in general, and those who think rigorously tend to do so as a matter of course. So those that think sloppily are diluting investment threads, and those that think rigorously are diluting the poo-throwing political threads. And of course, you who are reading this know you are a rigorous thinker. ;D
I think in a recent thread Sanjeev wrote that in the next iteration of this board, politics will be eliminated. I look forward to this. Even for the non-rigorous thinking posters, I suspect there will be a tendency to try to match the level of discourse.
