There's ways to integrate Mastodon comments, if that's up your alley. I don't know the technical details, but basically a Mastodon post linking to your blog post would show up on the Fediverse and when people respond to that post using the "public" privacy setting, then that post will show up on your website.

If you tagged a Lemmy community in that Mastodon post, it should also federate over here, although I'm not sure, if responses will also show up.

Unsurprisingly, there's a gazillion blog posts out there on how to set this up, but here's just a couple:

• https://berglyd.net/blog/2023/03/mastodon-comments/
• https://andreas.scherbaum.la/post/2024-05-23_client-side-comments-with-mastodon-on-a-static-hugo-website/
• https://lauralisscott.com/blog/mastodon-comments-hugo-static-site/

And of course, if you scroll down to the bottom of those pages, you can see how the integration looks like.

From what I've seen when quickly scanning the posts, I believe, they're using different plugins to do this. The first link I posted discusses a plugin developed by Carl Schwan, who's also a KDE dev and he's here on Lemmy, too, so that would be what I'd personally try, without knowing anything else about these plugins. 🙃
