WordPress powers the comment area of Jeff's site. This will be super easy to clean up with our CSS superpowers. We make a .scss file just for comments (the perfect example of where a Sass partial is appropriate). We include that in the global stylesheet. Then we tweak up the look of the comments by giving them space, adjusting the typography, invoking styles from elsewhere on the site, and removing stuff like the Gravatar which doesn't have much use on a site like Jeffs.
The comment form needs a touch of loving too. The full width textarea is a class example of where box-sizing: border-box; is a godsend.
