Interesting idea trying to integrate Mastodon and Lemmy. From the readme:

This is a simple script that monitors specific Lemmy communities and attempts to #hashtag new posts so that they are discoverable in microblogging services like mastodon.

By integrating hashtags, lemmy posts will be discoverable by those following those tags in microblogging which could lead them to reply, boost etc, something which will appear as new comments in lemmy. Since microblogging fediverse has an order of magnitude more users than lemmy does, the hope is that this will allow to kickstart a lot of more niche communities and deepen the interaction between the two mediums.

I’m all for it, even if it confuses the removed out of me that any Fediverse platform user can read and comment here from a platform with an entirely different purpose.
