Just wondering. Could be cool.
I think you can, by doing @piefed_meta@piefed.social
It’s almost the same as on Lemmy/PF except here we use ! on the front.
You can mention a Piefed/Lemmy/etc. community in your Mastodon post, and it will show up in that community.
For example, here’s something I originally posted on Mastodon, but made it show up in !mechanicalkeyboards@lemmy.ml by mentioning that community in my post: https://lemmy.ml/post/32525858
However, I heard that Lemmy ignores it if you mention multiple communities in the same post, probably to prevent spam. Not sure if Piefed does the same thing. I’m not sure how to get the same Mastodon post to show up in multiple communities. Maybe it just works if you mention multiple communities – I haven’t actually tried it.
Also, I don’t think there’s a way to make someone else’s Mastodon post show up in a community, which is probably a good thing (to avoid unwanted attention). Aside from just creating a post in that community that just has a link to the Mastodon post, of course.
Re: the Mentioning in multiple communities, PieFed does the same. Preventing spam is a nice side-effect, but the main reason is to handle the same activities being sent multiple times. The most reliable way to know if you’ve already received the activity for a post is to have a unique constraint on the DB field for the post’s original URL (so once you’ve created the post for one community, you can’t then create the same post for another community).
I was experimenting with adding other people’s mastodon posts to a local PieFed community earlier. It’s technically fine, not much different than another Mastodon user boosting the post. The slight difficulty is in getting Lemmy instances to accept them - you have to break their Group spec a bit to get it work. It might be worth doing anyways.
