I’m not sure if this is the wrong place to post this; my apologies if it’s not.

Anyway, I have an inquiry about Mastodon replies seeming to not post to show up on Lemmy.

Earlier today I made a post on Mastodon and made it post to Lemmy as well, by @ing the community I wanted it to appear in. Here’s a link to the post on Mastodon, and here’s how it showed up on Lemmy. At first, everything seemed to work fine.

But something I noticed is that, though the Lemmy comments were visible to me on Mastodon, the reverse was not true: most of the Mastodon replies were not visible on Lemmy. So there seems to have been some federation issues there.

So my question is, does anyone know what caused this and if so how I can fix it?

If I had made this post on kbin would the lemmy and mastodon users have been able to interact with one another?

It's more likely that the instance hosting the community would make the most difference. Try a PieFed community if you're interested.

I always an avid user of piefed.ca but I had to quit because most of my comments weren’t federating anymore due to some corrupted data issue

Edit: misread your comment. You jut mean posting to the community. Gotchu

Good to know thank you! Piefed seems to be doing a lot to help the fediverse grow, so thank you for your service 🫡

Now that the issue is fixed I need to make a new account or will it work with the old account too? Also I noticed that my profile photo from my old account isn’t federating haha, but that’s a very minor issue so I’m not too concerned about it haha

The federating issues were solved iirc

Theoretically yes.

Practically, only sometimes. Mastodon doesn't know to send the reply to the community (or even just a user from that community), so when replies are made that don't include the community, then they don't get make it through to the threadiverse.

Mastodon users (if they're following the community) will get everything, but the UI for reading threadiverse content is abysmal 😝

Haha okay. Thanks for the info!

lemmy does not federate with mastodon/the twitterverse..

i believe there is a one-way mechanism for twitterverse posts to be used an inbound content stream for lemmy (like rss ) but thats it... one direction.

i dont think theres anything you can do to make that happen short of some janky bridge.

i subscribe to lots of peeps from the twitterverse.. i can reply to/comment on posts, see other comments, upvote/boost, etc.. kbin is dead long live mbin.

The Lemmy posts were showing up as replies to my Mastodon post. And some of the Mastodon replies were showing up in Lemmy. So it does seem to go both ways, its just inconsistent

If you use Misskey or whatever it calls itself now, it works well with Mastodon and okay with Lemmy.

[–] a_gee_dizzle@lemmy.ca 1 points 4 months ago (1 children)

If I had posted this on Miskey would that have allowed Lemmy users and Mastodon users to interact?

[–] hzl@piefed.blahaj.zone 1 points 4 months ago (1 children)

Eh. Not really very effectively. Misskey does a half decent job of talking to Mastodon and Lemmy, but Lemmy and Mastodon do a pretty poor job of talking to each other and I think Misskey is more compatible with Lemmy than Lemmy is with Misskey, if that makes sense.

Okay thanks for the info
