First off, I love your theme. I am using it on a feminist game blogging site, and having some difficulty with the threaded comments.
If you look at a post with a lot of comments, you can see that they start getting so nested that the columns are really narrow. It doesn't look so bad at full-variable-width, but when people make the page narrow it looks horrible =(
You can see this thread for an example of that. I made the font size smaller to make up for this, but its not the optimal situation, especially since the site is read by people who have vision impairment.
Does anyone have any tips for maybe reducing just how nested the comments can get? I don't want to switch to non-threaded if I can help it.
