Thanks! I spent a good while fiddling with all the styling, so even though this site is pretty slow, it's nice to see that people appreciate the work that went into it.
The replies at the bottom is a tweak I made to the vichan show-backlinks.js script, because I thought it looked nicer than the default one. The exact details vary by browser, but if you open your browser's debugger on this site and find the show-backlinks.js file, you can compare it to the stock vichan one and copy my version if you like. There are some other changes in the file, but the section in pic related is specifically what moves them to the bottom and adds the divider line.
