[jacebenson]

Since you've gone and done the hard work of updating the commenting stuff to allow for different engines, if you'd like I can whip up a PR for https://utteranc.es

It claimes to be a;

If anyone is here hoping to find a quick answer to the question of how to just add utterances, see my comments towards the bottom of this great blog post on the topic: https://masalmon.eu/2019/10/02/disqus/

Basically: just replace everything in layouts/partials/comments.html with the code snippet from utterances.

I had created a PR to add this to the repo but was directed to make a plugin. https://github.com/wowchemy/wowchemy-hugo-modules/pull/1364 That code may help others either make a plugin (I got lost there) or add it manually to their site.
