May I suggest getting rid of the overridden arrow key behaviors? I don't mean to sound harsh, but I gave up trying to read the post because the behavior of "up" and "down" is weird, unnecessary, and comes with an obnoxious animation. I figured out what they did pretty fast, but then I'd lose my reading place by absently pressing "down" in an attempt to scroll the post. Also, the blue bar might work better if it spanned the entire width of the right column and fixed to the top of the content area. Right now, because of the content that appears above it and all the white-space to the right of it, it feels like it's floating over and blocking content.
