I'm not too much a fan of the animated ads; however, the site overall looks fine. If I am correct in reading your intentions to publish free resources, it's absolutely expected the site, and your efforts, to be funded by ads. I use a 2 monitors. On the smaller monitor (1280 x 800) the layout is fine. And on the larger (1680 x 1050) it looks like it could even have a few more. Maybe text link right across the top, or right below the "content" area. Great job. I'm a fan of the minimalist themes, and you dont see too many of them anymore.
Did you remove the ads? I only see one ad on top and one adsense ad on the right column. It looks very nice.
