Describe the solution you'd like
Webmentions are an open standard for a protocol to notify about links, likes or comments to a webpage.

Additional context
So when you add a link to a website, you can send a Webmention as a notification to the linked page. Like a reference for the author about your reaction. So authors can get notified when they receive a linkback, comment or a reply.

Webmentions can be implemented from this tutorial

I think webmentions do require a server to render latest information on the go.

There is a plugin to add webmentions to jekyll blog but I think it only adds the data on build time, which is not assured to be up to date unless it is built on a set interval.

With the latest inclusion of giscus in the theme, we have the comments section back. This basically enables user interaction on the site once again. I will leave this issue open for discussion, but as of now I don't think web mention would add more "interactiveness" to the site.
