Good idea. But I think the main problems is people itself. Look at the post that you quote.
Right now we are having tons of replies in threads that are repeating the same shit. Pushing people to have at least a small conversation wll be much better then nothing.
For some reason it seems like everyone is trying to find an ultomate method of moderating the forum that will solve all our problems in a minute. You won't be able to build a decent community this way.
