So this acts as an ActivityPub inbox (comments) and outbox (publications)? Brilliant! I had been toying around with the same idea the past few weeks.

Go ahead and try searching for @BaptisteGelez@baptiste.gelez.xyz in Mastodon, then toot-reply to one of the article toots (from Mastodon) - your toot will show up on the blog post as a comment after a few seconds and a refresh.

Great work!
