This is a pretty minor issue:
I was browsing Writers site and noticed the line-height for list items is inconsistent with other sites (like SO). It is 16px instead of 18px. I noticed because I was having difficulty reading this answer. This may affect other sites as well.
Proposed resolution is to increase the line-height to aid readability. It may be advantageous to add a small bottom margin as well, but not strictly necessary.
The line height is set in all.css, line: 136
