It's a good layout. But it needs formatting esp. in the sidebar and POSTS footer and the FOOTER area. enjoy
Personally, I like warm colors over cold, but I think it looks pretty good. The centered page is to my liking. The only thing that caught my eye was the "more articles" near the bottom, shoved to the left edge. All your other text is indented aligned.
looks fine on my res no scrolling. I suggest a background image, something dark blue and techie repeating down the page on both sides.
It is not bad however I think the main navigation, side bar navigation could be improved as well as the blue links in the footer.
