I would register your own doman, drop the adsense from the top as the double/tripple adsense knocks down the content. Also I recommend a new style and maybe add some colour. Content seems good though. Just needs a quick tidy up
remove the 1 of the ad blocks from the top, and the 2 bottom ads (U wont' get any clicks there). Any blog with content should try this placement- large rectangle inside the content of every blog post for highest ctr
