How do you do this? I’ve seen others mention it but I’m confused on how you actually do it.
Not just linking to Mastodon, but seeing the Mastodon post from PieFed/Lemmy and being able to cross comment.
I’ve seen a piefed user’s posts show up in my mastodon feed. Near as I can tell, after asking them, it wasn’t intentional on their part, but they used a hashtag in their piefed post that I was subscribed to on mastodon and that was what caused it to get pulled in.
It was especially confusing at first because neither my mastodon client nor my Lemmy/piefed client displayed the hashtag.
I don’t think this answered your question but thought you might find the info useful.
Lemmy sends out the community name as a hashtag to Mastodon, so this post is tagged #nostupidquestions. The hashtag isn’t visible, but the post shows up in the tag timeline nonetheless.
That’s really helpful to know.
It wasn’t the case in my situation though.
The post was in /c/historyruins@piefed.social and the hashtag I follow is #thailand.

Oh most definitely, here’s this post on Mastodon:

Still unsure of how to do the reverse though.
Ok this ‘appears’ to work. Each community is viewable as a group in Mastodon, so you can tag it as you post and this creates a PieFed/Lemmy post onto PieFed’s testing community.

Now to figure out the final step, how to crosslink posts.

What do you mean with “crosslinking” in this context?
You know how to view a threadiverse post from Mastodon. You know how to post a Mastodon post to a threadiverse community.
What else are you looking for?
My aim was to take an existing Mastodon post and basically repost it somewhere else here on Lemmy, but then have the discussion attached.
For example, John Mastodon makes a post about XYZ, then I crosspost it to the Open Source community, and if you open that post you can see the Mastodon comments and such, and commenting here on Lemmy would add to that conversation.
Can you do that with Lemmy/Piefed posts?
Yeah here’s an example from yesterday:
This is posted to /c/memes@piefed.world and /c/memes@europe.pub, marked by this stacking icon thing.
You can see the comments from both communities if you visit either post in either community.

What do you mean?
Any post, on any service, is technically accessible on any other instance, running any service. Actual implementation, varies.
Unless you run into it in the feed, the way to find a given post is to enter the original instance url for it into search on the instance from which you want to interact with it.
To upvote this post, for example, even from an instance that it hasn’t federated to, I can enter the url to this post on its host instance into search, and the other instance will fetch the post, allowing me to vote and/or comment.
Same goes for mastodon toots. Get the url, put into search, upvote, comment, whatever.
