Does something like this exist? As far as I can tell, setting something similar up would require:
- A dedicated Lemmy instance for Mastodon tag-based crossposting (probably, since most existing instances probably don’t want to clutter their instance with thousands of script-generated communities)
- Some kind of form on a site where users who want to follow a Mastodon tag that is not already set up as a Lemmy community could submit the tag they want added, which would automatically set up:
- A Lemmy community for that tag on the aforementioned instance, and
- A Mastodon hashtag bot that automatically crossposts all posts with that tag to the linked community
I’ve been suggesting the use of tags to interoperate with the wider fediverse since lemmy started. The have reasons they don’t like it but there seems to be some discussion moving forward on them in side channels. One of the devs asked for an RFC on a hashtag implementation and someone submitted one, though I haven’t seen any feedback on it and it was not a solution I really liked.
That’s good news
