The google ad right in front of the eyes on the front-page is a bit of a turn off, instead of such high quality articles you have written. That one banner tends to dilute the overall quality in the first look itself. Also because your menu bar is black the ad looks more prominent due to high contrast. May be you should think about moving it to a sidebar or come up with some other alternatives.
The header image needs a little work i guess. Key highlights of the blog looks randomly scattered as of now, you could consider at least to display them in order. I am sure you will come up with something creative and nice to look at that will help people stay at your blog.
p.s - The domain name itself is a keyword having over 2,110,000,000, results and comes in first page on third position, which is awesome..so the blog definitely seem to have a very bright future.
