What exactly is an applause light? Based on Eliezer's post, I see it as a description of a goal, without any specifics on how to achieve that goal. I'm not sure I see that in this poster; the poster presents an implied suggestion on how to reason better (look for fallacies like these in the speech of yourself and others).
If you're suggesting that being able to avoid these logical fallacies falls out of reading Less Wrong automatically, and the poster is therefore preaching to the choir here, that's a different allegation.
Applause lights are when you say a meaningless or almost meaningless phrase meant to evoke good feelings about your position. "Freedom" "America" "Democracy" "The greater good" etc. The poster is really more to make you feel good about yourself and your knowledge of biases than for anything useful.
