I saw a talk by the peole working on FrontPage last week, they use the Bluesky Relay, filter it down to only see the posts they're interested it, and have their own AppView. It doesn't yet have the same kind of intereoperability with Bluesky that Lemmy does with (say) Mastodon; FrontPage posts are only visible to FrontPage. But, there are discussions on how to get beyond that.

I guess technically Bridgy Fed is also using it, allowing content to be bridged between AT and AP.

[–] Fitik@fedia.io 3 points 3 months ago

True, but I see it more like a BlueSky PDS (instance) than a separate service build on top of AT protocol

Btw you can even follow Bridgy from MBin, but federation doesn't work very well @bsky.brid.gy@bsky.brid.gy

No, because the AT Protocol is not designed for interoperability, but rather for entrenching the silo owned by the main node (BlueSky) whilst giving the illusion of being decentralised. It’s to decentralised social media what Microsoft’s OOXML file format (tl;dr: a memory dump of Microsoft Word’s internal data structures encoded in XML, and useless to anything that’s not Microsoft Word or a very precise emulation thereof) is to open document formats.

I don’t understand what the words in your comment mean? Can you eli5

Someone shared different services using at protocol already

Link aggregator similar to lemmy: https://frontpage.fyi/

Blogging service: https://whtwnd.com

Both of these services appear to be dependent on BlueSky. I.e., if BlueSky ceased existing, or cut them off from its API, they’d die. In that way, they’re not that different from “Log in with Facebook” or similar.

One could theoretically make one’s own independent AT Protocol network, but not in a way that interoperates with BlueSky as a peer. You’re either a subsidiary part of its network or you don’t exist as far as it’s concerned, which is a much poorer value proposition than ActivityPub and related protocols.

Are you talking about blusky's indexer?

[–] Blaze@feddit.org 9 points 3 months ago

They are the only ones IIRC

[–] ericjmorey@discuss.online 2 points 3 months ago

Not yet

Video platform (like FediMovie): https://www.bluemotion.app
Audio streaming: https://www.bluecast.app

[–] xnx@slrpnk.net 1 points 3 months ago (1 children)

Awesome thanks! Where did you find these? Do you know if comments or posts show up in bluesky too?

[–] Kierunkowy74@piefed.social 1 points 3 months ago

I did not check Bluecast, but Bluemotion videos appear on Bluesky as links to page of that video on Bluemotion

And it looks that Bluemotion will not attempt to compete with You/PeerTube: the creator plans to end the service as Bluesky started to support video posting
