Broken themes

My blog’s theme is displaying in a haphazard way, but only on the home page. The sidebar is at the bottom of the page, most of the text is bold and the color of some post titles is changed. this is not only the problem of the theme I am using, but also for other themes. I am using wordpress 2.6.
Can anyone tell me how to put this problem right? Any help will be greatly appreciated. You can see my problem yourself at footiereview.com.
