Could you make a community, and a bot? The bot would look for any post on your blog, then the bot creates a post in that community that uses the blog post title as the lemmy title, and uses the blog body as the post body.

Then the bot tells your blog the url of the lemmy post to use the lemmy comments.

Then, I see the button that says “load lemmy comments”. Maybe your bot also creates a mastodon using the title of the blog post as a link to the blog post. Then any mastodon replies to that mastodon post could be under a different button that just says “Load Mastodon replies”.

So at the end of your blog you have “Load Lemmy comments” (just as we see here) but next to it is “Load Mastodon replies”.

And all of this, is done by you just posting once to the blog, while the bots do everything else in an instant.

You just post once on the blog, and automatically a Lemmy post is created which is a duplicate of the blog post, the lemmy comments are loaded via a button on the blog automatically, a Mastodon post is created which is just a link to the blog using that posts title as the clickable link, AND a button on the blog is created to see Mastodon replies to the mastodon post.

Everything besides the innitial blog post is automatic.

Is that possible?
