i think the ad unit blow the lnks is pretty good, but need suggestions for the unit above the posts http://ronswerdfiger.blogspot.com/
yeah the ad link on the right column is good, but the top 468x60 isnt too great. Try integrating them withing the articles, same font color, etc
Rectangles often do well when placed after the first few paragraphs of an articles. Allthough it may be difficult seamlessly integrate it with your site.
<div style="float:left"> [adsense] </div> some text here. Code (markup): This should achieve an effect like you have in the PS3 post.
This is how it looks in my browser (IE, Firefox). For the text above the image. I simply added a bit of text before the <div> tag.
