I'm glad to see that Slope isn't the only corner of the web dedicated to giving the citizens of the United States at least a 3rd grade education when it comes to spelling, grammar, and syntax.
This has nothing to do with charts, I realize, but I'm still recovering from seeing the ridiculously dishelveled and rumpled Mayor of London at the closing ceremonies last night, looking like a buffoon as the elegant and poised Chinese Premier and IOC Chairman passed him the Olympics flag. Wow.
