Like I said when I made that post from my lemmy.ml account, this is not supposed to be a judgement against lemmy.ml or it's admins. I have no interest in participating in instance drama.

So, I would appreciate it no one posted about this migration on [email protected]

In terms of infrastructure, Bluesky does seem to be capable with keeping up with the current level of 5,000,000 posts per day by pouring money into their relay. What I'd like to know is the cost per user of Bluesky compared to a centralized service like Threads.

I think one of the bigger issues with Bluesky scaling is moderation. Mastodon admins only have to deal with moderating their own instance, while ATProto labeling services can receive reports from any and all Bluesky users. So far, most people who attempted to launch an independent replacement for Bluesky Moderation Service have failed to keep up with the volume of incoming reports. Usually, they have to narrow their scope and focus on very specific issues, like Laelaps, Asuka's Anti-Transphobia Field, Blacksky Moderation, and AI Mod. However, as Bluesky grows, I even expect them to be unable to keep up.

Neat! Does that mean there's an ActivityPub equivalent to the ATProto Firehose?

They're actually both using ATProto. The difference is that Reelo will be hosting their own video uploads instead of relying on Bluesky PBLLC, meaning that users won't be subject to the 60-second limit that Bluesky imposes.

It's a private company that has no affiliation with Bluesky. It's no different than services like mastohost.

Normally I'd agree, but the recent increase in popularity of Pixelfed among the TikTok crowd has shown me that it's possible for one fediverse platform to succeed where a competing one failed.

Basically, on ATProto, everyone stores their own data on a PDS (Personal Data Server). This includes every post, image, video, follow, like, block, etc. The relay crawls the open web for PDSs to consolidate into a single stream of data.

From here, services can build off of that single data stream without needing to do any crawling of their own.

Of course, this does give the operator of the relay a lot of power. If they were to block your PDS, then only services relying on a different relay can access your data. This is especially why it is important that there exist independent third-party relays, but no one has taken up the mantle yet.

Diversity is good

ATProto is not nearly as mature as ActivityPub. Businesses are only just now launching ATProto services (Graze being among the first notable ones).

There is a blog post from a dev about running a relay.

Fun fact: ~~Bluesky was originally started at Twitter.~~

But can ActivityPub scale?

There are many types of Bluesky servers. This post is about ATProto Relays, which consolidate all the data across the network into a single location. They are necessary for efficiency, but they are extremely expensive to run. Currently, there is only one ATProto relay, but there is an initiative to launch a third-party relay.
