I finally switched the appearance of the site. I was rapidly becoming tired of the old theme, which was too dark, overly imposing (which detracts from the content), and hard on the eyes.
The new theme, in case anybody is interested, is a heavily modified version of WordPress’ Twenty Eleven theme. It takes surprisingly little time to modify it to look completely different than it does out of the box.
I also used a number of typography cues from a web marketing site called Social Triggers. You can see the specific post here. The goal was to make the site easier to read, which I hope this accomplishes.
