I have this set up on my blog www.ashwinmenon.com

You can inspect and see the JS. There are a few others doing this too!

Thanks Ashwin - very helpful!

I think webmentions would be the answer there, though I don't think Bluesky currently supports it so you'd be looking at scraping rather than a push-based model.

you can just post a message on bluesky and link it to your blog post at the end with some text saying "want to comment? Reply to this post."

Personally, I prefer using webmentions. I got them back to my site using a combination of services, so if someone talk about a post I made in bluesky or mastodon, I usually get a webmention back to the post.
