I know a rhetorics teacher at my uni who will marvel at this idea! Seriously, for practical rhetoric teachers this site will provide a good segway into the rhetorics of excuses and to a lesser extent ethics.
i actually noticed a lot of people downvoting "excuses" and decided to switch the positions of the vote up and down buttons. Previously, the vote up was on the left and down on the right. I'm curious to see if the votes will now swing the other way ;)
