How Lemmy could interop with Mastodon, as imagined in Frontpage + Bluesky


Hey 👋 if you don't know us already, we're building Frontpage; an AT Procol based federated link aggregator. We shipped an initial MVP in closed beta recently and have since been thinking about the road to general availability.

This post is an RFC (Request for Comments) targeted at technically minded folks who are interested in seeing the progression of atproto for non-Bluesky/microblogging use cases. All that's to say the language that follows assumes some knowledge about how Bluesky and atproto work! I've tried to include links to explain what all of the jargon means though, so hopefully it's not entirely nonsense for folks a little less familiar!

When you post on Frontpage, we propose that a mirror post will also be created in your Bluesky account. When you comment on Frontpage, we propose that a mirror reply will be created in your Bluesky account.

Conversely, when you reply to one of these mirrored posts in Bluesky - we will show it as a reply in Frontpage.

Additionally, Bluesky likes will be translated to Frontpage votes and vice versa.

Cool to see things being built with AT. For what my thoughts are worth, I think that having Frontpage posts showing up on Bluesky would be benificial. It'd probably make it feel like it has a lower barrier to entry and increase interactions/discussions across the different communities.

P.S. replying here with Friendica which is taking advantage of similar cross compatibility.

Also, just a curiosity, how good is AT's cross compatibility without workarounds? Obviously if you guys are considering I assume it works, but I've been curious how well things play together. Nostr has NIPs to solve the issue, and ActivityPub is a little tempermental, but with AT's repo style accounts I've wondered how well everything interacts across different implementations.

Fediverse reshared this.

If I understand correctly, there's a central pump running behind the scenes in any AT implementation. You feed content into the central hub, and it pumps it out to everyone connected to it. Bluesky itself provides the one major pump that feeds its network right now.

So in that sense, Bluesky is a centralised network with decentralized users.

Frontpage is building a different pump, spreading different kind of content to a different type of platform. So there's no obvious connection between the Bluesky pump and the Frontpage pump - that's why they're talking about bridging in the post.

It almost seems a bit silly - in order for two AT hubs to talk, you need to build a bridge for them. At that point, you could might as well have built an AP protocol and made it work with Bridgy.fed.

Furthermore, all "instances" running Frontpage would process data through the same central hub. If that goes down or they run out of funding, it's all over.

I'm applauding the Frontpage crowd for trying something new. But I'm not entirely convinced I see the benefit compared to what we're doing over here.

Unpopular opinion: IDK why people want perfect interop so much, I have a Mastodon account and a Lemmy account, big deal. We've got bigger fish to fry than this. The formats are different enough that you're better off having separate accounts for microblogging and threadiverse.

Interop for similar platforms is a great feature, but for dissimilar platforms I don't think it's actually necessary just a novelty. Also I think people try to push this on new users as some big, useful, important feature, but I think it only confuses the new users.

Also I noticed most of the time when people complain about ActivityPub interop issues, it almost always ends up being Mastodon's fault lol. Probably because they were early to the party and didn't have to worry about interop and standards much back then. At least I hope it isn't malicious lol.

Don't think this opinion is unpopular at all. It makes sense for platforms that are similar to interop.

Hypothetically like Youtube interop with Peertube (video platforms) or Instagram interop with Pixelfed (photos). Or Threads, Reddit and Lemmy (forums). And Mastodon and Twitter (sorry, but just making a point here 😁)

But yeah, see no reason for interop between platforms with completely different purposes.

You can reply and interact on platforms from an RSS reader. All an RSS feed is is a list of links. When you click them, you go directly to the platform. When using on a mobile device, RSS readers will even open the app for you to reply or interact with posts.

The fediverse will never replace RSS feeds. They serve a totally different purpose.

I think support for boosts is a game changer for interoperability. As a Mastodon user I wouldn't really want to follow a community even if it was well implemented, but I'm happy to follow users who boost content I'm interested in.

Boosting content is the way posts spread on Mastodon. If anyone follows me from Mastodon they will see all the content I boost; if they enjoy it, they might re-boost to their followers and the ball starts rolling. And that's how you suddenly get comment sections where Mastodon users are actively participating.

The only issue that makes this interoperation unusable really is that Mastodon groups representing Lemmy communities just “retoot” every single comment, obliterating the TL of anyone who dares to follow those groups. Which as far as I know only happens because Mastodon refuses to be cooperative and properly follow the standards.


Pleroma/Akkoma deal better with this, The groups there only retoot the main topic, and the answers you only see If you open the main topic, then you see all the threads.

One thing that seems to go unappreciated in the comments is the simplicity of this interop proposal: It is essentially about enabling quote-posting of link-aggregator(Groups) posts.

Bluesky + Frontpage will work this way, and I believe it’ll work exceedingly well. If the ap-net corner of the fediverse isn’t interested in this kind of interop, fair enough. To me however the promise of seamless interop between my social apps was what brought me to the fediverse, so that’s the version of the fediverse I will pursue.

That's fair.

For some other people the appeal of the Fediverse is to be able to manage the instances themselves, and Bluesky still isn't there yet on that side (and probably won't, as it would prevent them from generating revenue if someone can just open a server and connect to their network)

I don't think that's necessarily true. As fas as I know there are no plans to inject ads, they are planning to create a marketplace for custom feeds (think "premium" feeds) and labelers and such where they would take a cut. You would obviously still be able to purchase access to them from other servers. But this goal seems kinda lofty, not sure if it can be viable.

The 2 largest mastodon instances both misrepresented involvement or intent with Meta to their users, then turned around and federated.

Those were/are the best chance for the fedi to leap forward.

They are the most popular and also now the keast likely to be used by tech people, both because if the association and because they misled their users.

The admins of those, one of which is the masto dev, have arguably done more harm to the fedi than anyone else. People left for bluesky right after the bragconfession and openly posted about why.

So it's not in the room with me, because I dropped their scene and closed all my accounts.

It takes a moral village idiot to compromise the whole environment just to grab some cash for their subsequent honeymoon. Not unlike current Twitter management thinking, and not unlike social media thought-levels in general.
