The current site style was selected because it's fairly simple and provides a good bit of space in its layout, even if it is rather plane.
Irregardless of the finer details, the ability to coop with content breaking out of their boxes is somewhat of a necessity. I often post snippets of code, command output, or even action logs here, from whenever I'm working on my own crap. Although my terminal runs 80 columns wide, there is no such garruentee when I reach for the pre tags. Because of how Blogger handles titling untitled posts, much the same applies to the archive barlet.
I don't have any problem with web design, although I prefer working on server side code rather then doing the visuals, should we say, I find it a more rewarding experience for the amount of effort I put behind coding.
