i would put your adsense ads into one of those blue-bordered boxes to make them blend more into the page.
I like the overall clean aspect of the site. However, I think you need a new banner re-design. It just doesn't 'fit in'. Something is missing.
I agree that you should blend your ads more to make your overall site look better BUT, keep this in mind too because it's very important, You DO want your Ads to stand out within your site. If they blend too much, people won't see them as much and you won't get as many clicks. For example, on my site I use mostly blues and whites as font colors but my Ads are all in black.
Great subject. But I agree with slaydragon. It needs more excitement it now looks like a bad hangover but a few tweaks here and there, change the color and background images, everyone will be drunk forever.
Thanks for all the advice. I have made some changes. I think slowly and surely it will look better. Any want to do a free logo for me?
