This blog is statically-rendered using Hugo, which means there's no easy set of plugins (that I know of) for adding Webmentions. There's nothing like the IndieWeb plugins for WordPress. I've been collecting webmentions for a while via webmention.io but needed a way to render them here. I decided to go ahead and roll my own.
I'm sure I'll want to dial things in, but this is a fine start. Thanks Karl!
