The section of your blog above the fold (what you visitor see without have to scroll down vertically) is the most important part of your blog. Businessmen like ground floor shop space, and that section above the fold is like ground floor shop space. Just as shoppers are lazy to walk up the stairs the second floor (the third floor would be worst), surfers are often lazy to scroll down your site to see the rest of the page and will quickly surf away if nothing catch their eye. So depending on what your objectives are, you should try to put what you want your visitors to see first above the fold. And the best way for you to do this is to use a 3 column template and not use a deep graphic Header that takes up most of the space above the fold. You may find it makes your blog attractive, but you will be unable to put many things above the fold.Sometimes you are forced to compromise, like I compromised by putting a sitesearch box at the top of the main column above the post. But I feel it is useful because visitors can't miss that and hopefully they will use it to find topics in my blog and thus stay in this blog longer than otherwise. I think it is a worthwhile sacrifice. If you want a similar sitesearch box, you will need a Google AdSense account. You can apply for one via the "Generate revenue from your website. Google AdSense" text link at the top of the right sidebar of most of my blogs, including this one. (sorry, I got mixed up with my other blogs. I was forced to put it in the Header section because I set it so that visitors can search the web, this blog as well as 2 related blogs of mine. This made it too wide for it to fit into the main column)
