Well...for starters how about citing sources? If we were writing a paper for a class we would be expected to list our sources and reference them appropriately.
Obviously statistics and sources can be biased, but getting into the habit of citing sources to back up our statements forces us to actually review our ideas more thoroughly.
We can also use the forum to sharpen our debate skills. Learning to structure our ideas properly would improve the quality and amount of information passing between us.
