If you mean what the comment section looks like on the page with default templates and css, I have it almost default on my site. The default styles were close to matching the rest of my site so I didn’t change them much. You can see it at the bottom of the page here:

I did make a couple minor changes. The comment titles were larger by default, I made them a bit smaller. The comment poster’s name is not bold by default. Jot shows the comment poster’s post count, but I took that out as it wasn’t working correctly. Each comment by default had a top margin of 10px, I added margins to the sides.
The actual comment form is not styled, so it’s using the site’s css for the forms. But everything else on the form is the way it is by default, except I added the (will not be published or shared) to the email label.
Other than that, that’s the way it looks out of the box.
The Reader Comments: heading I have there is not part of Jot.
