Open Lemmy comment threads in Mastodon? (sopuli.xyz)

Since both lemmy and Mastodon use the fediverse, is it possible to view comment threads under posts from lemmy in Mastodon? How to find a link that works in both/ is it related to the posts id?

Would these work with #hashtags ?

You can find Lemmy posts on Mastodon, yeah, but only if it's been federated there.

In regards to Lemmy, there's two means of federation I'm aware of:

  • When a user of a Mastodon instance is following a Lemmy community, posts made to it are federated to their instance.
  • Any registered user on a Mastodon instance can enter the URL of a Lemmy post in their instance's search field to actively federate it in

You should then be able to find the post on Mastodon either over the community's profile, via potential hashtags used in it, or possible the author's profile if that got federated over too (idk if this happens automatically).

If the post was made by an Mbin user, then there's also the option to follow the user directly instead of the community the post was made in. Not sure if this also applies to Piefed, but definitely doesn't for Lemmy.

For example here is a Lemmy thread: https://discuss.tchncs.de/post/41964952?scrollToComments=true

Here is the same thread on Mastodon: https://floss.social/@kde/114960515064007515

So it is possible if it has been federated to both. There are different reasons why that might happen, in this case it is because that thread's OP posted it on Mastodon but mentioned a Lemmy community.

Another reason why it might happen is that a Mastodon user is following a Lemmy community or user.

I see this post on Akkoma by #Fediverse and answered it. Another person from dot social on Mastodon also commented it. It's weird that those comments can't be readed here in the post. I've tried to comment from there before and seems to work. So I'm not sure what happens when you interact outside of Lemmy.

yes get original link by fediverse icon and search on your instance it will appear if federated.

Yes, you need to copy the Lemmy link (original link), I think it is a colourful Fediverse icon on the default UI.

Search for that URL on Mastodon and it should appear.

You might not see all the comments though, depends if they have federated (you can search for them as above).
