Please Review My Blog,what you thing about this blog? im expecting your review? find my blog in my signature....
The design can be improved. About SEO, you haven't nothing yet... Where is the keywords, the description, etc in meta tags?
Useful only has one "L". I agree, the black background is bad. Consider something with a white background. I do like your sidebar. I think Google adsense only permit you to have 3 instances of adsense per page. Your articles have more than this and thus your account may get banned in future.
Instead of having bright green, I would pick up the gray from above and follow through. Th.en the gray question mark on the white background in the square, I would try either black or pick up the same blue that you have on the black computer on the right. Check that out for starters and then let us evaluate it again. I think the Green definitely needs to go. I actually like the black background. You just need to get rid of green and tie the colors in to co ordinate with each other to keep the eye of the viewer flowing in your page. Imagine your page is a piece of art and you need to put these design rules to use. Cheers to your success and Properity
