Hopefully it won't be noticeable at all, but I increased the width of the right column to 300 pixels wide to accommodate the better-performing Google AdWords 300x250 ad instead of the previous 200x200 ad.
I also started running an ad in the HeroMachine 2.5 application.
Finally, I'm working on a method for running an ad in the designated HeroMachine 3 space, so be forewarned. I tried this before, but had trouble getting the ad to not show when you're in widescreen mode. But I'm working on it.
