Based on this discussion, I may also move my 336x280 ad to the right of my content. The main content of my landing pages fitss very nicely next to a large square ad for 1024 and higher resolutions (and 100% above the fold, so I feel this algo is targeting my site a bit unfairly.) I had the ad on the left because it tested 1-2% more revenue there. If folks think that right vs left could be a factor here, it sounds like a no brainer to move it to the other side to avoid the penalty.
