Put simply, the sorting / ranking is based on the score and the time published, so as long as things are getting federated within a few seconds, then federated posts / comments are no different from local ones. Mastodon only sorts things by newest AFAIK.

That implies the All feed is unique to each server, and therefore all of the sorts are also unique. Which would mean for at least a certain percentage of posts, they might be in your hot or active feeds, even though no one is really interacting with them much any more.

Should only be an issue if your server blocks other ones.

So is the All feed actually all communities and not just ones federated to your instance by virtue of someone on the instance subscribing? That was really the crux of my question.

[โ€“] [email protected] 4 points 4 months ago (1 children)

Ah, this is completely different and has nothing to do with sorting. All means the latter, IE communities connected to your instance, that your instance knows about. Lemmy doesn't crawl anything, federated communities need to get subscribed to first, then posts can start coming in for them.

[โ€“] MagicShel 1 points 4 months ago (1 children)

Yes but also no. Because if the contents of All are unique to each server, that has some implications for which posts appear in the various sorts, right? Maybe I'm overthinking and the effect is minute, but I feel like in at least some cases it would mean less active posts could squeeze out more active posts.

Its best to just think of them as separate to keep it clear. Sorting affects all posts (federated or not) in the same way.

Alright. I appreciate the conversation. I feel like I'm not getting my point across, but that's cool. I'm not going to keep bugging you. Thanks again!
