I decided that my blog looked too... basic. I hadn't done much with it beyond the template, aside from some widgets.
The banner picture certainly livens things up. The beige-on-brown look was very studious and academic, but there's nothing like a splash of color to make the place look homey.
I also de-cluttered the sidebar, and made a few other changes, to increase the customization process.
Ahhh.... that's better!
