When building a site it is nice to know about your users. The more you know the better. Not on a personal level but in terms of how they are viewing your site. This is only a small piece of what you should track
I use AWStats for mine. This allows me to know the actual screen resolution thus I can build the site to the bulk of the general population.
You might want to try reducing the side bar(s) to 10% I think the code on the first page was 15%? Are you using the left side bar as well as the right?
What I would like to see someday is somehow dynamicaly display a site based on the users resolution.
