hmmm nice article....but strangely enough the best gamers i know who are at the top of their league to me displays some horrendous behaviors...most well mannered individuals tends to be at mid level skill...but that's just my experience
Look at DeViOuS, Ronstar, MysteriO and Nazy. When they're playing SC2, they're completely focused and you don't hear a peep out of them. Also well mannered (most of the time).
