This is really cool Lorenzo!
I’d like to suggest you take a look at the indieweb movement.
There are new technologies, like webmentions that you could use to implement likes and reply in a federated way.
And a static site like yours (or mine), can leverage https://webmention.io/ as a free backend.
As an example, this reply was posted on my own site, and syndicated here on your Disqus.
This post accepts webmentions. Do you have the URL to your post?
