Hey Chris, I saw the webmention from you. My comment system is implemented using a Perl script that uses the PoE::Wheel::FollowTail perl module to tail the nginx logs and look for /@say/. It then checks what file path was commented on. If in the /library/ it appends to the comments.html in that directory and writes to the main /hello/comments.html like every other path. Otherwise just /hello/comments.html. In my nginx config I use a little regex+location rewrite to handle the redirect when people comment: location ~ .?/@say/ {rewrite .?/@say/(.+)$ /hello/$1 last;}
