Hi, Nice blog. I think that you can try to move the AdSense Ads at your sidebar to place above your post. This way the AdSense Ads will get more attention and you might get some clicks from it.
i would say make the link color a little bit lighter blue to match ur title names and the green links change them to black so it all looks together cuz nothing else is green on ur site
First of all, you got some great content on your site! As nspstudio said, try to change the title color to a lighter blue. Also, try to add some horizontal ads to you site to. I would add one above the first post.
