Overall your blog looks good.
2 thinks I would work on:
1- Home page is a too busy, you might want to tone it down a little.
2- You need a tag for the home page. When I started navigating through the site (you had quite a few interesting posts), I couldn't go back to the home page.
Good Luck & Happy Blogging
thanks for the feedback. I will definitely try to work on home page. I added many elements since I wanted to be current and latest all the tim. As for the tag, the home link is there from all pages. It is fixed and is a part of the header top nav.
