the amount of low-effort drive by comments and off-topic posts communities gets just because they are similarly named is bad enough as it is.

which is why I actually want it.

I think a well-cultivated list of quality communities that people share is a means to escape the heavy amount of noise that grew out of the explosion in the number of low-effort barely-any-moderation instances.

Another way to look at this feature is really simple: multiple subscribe lists, the ability to organize what you subscribe to into your cultivated groups. I don't see why anyone thinks a limitation of having only one community list per login is beneficial in organizing the duplicate choices all over the place.

why does a multi-reddit need multiple instances to collaborate to create the feed?

by "create the feed", I assume you mean "provide posts" when API call post/list is called?

content is replicated in all federated instances. You only need to use the local copy and merge all the communities of the multi-reddit.

Yes, that is what MultiPass would do, query the local PostgreSQL database. Right now Lemmy only allows this for a single Subscribe/Follow list per user... you have to create 3 different logins if you want 3 different lists of communities. For example, a "games" list, "music" list, "news" list.... Plus, the current design does not accommodate logged-out users, they have no way to list multiple communities (other than "All", local or merged remote+local).

Multi-reddits as they exist on Reddit itself could be implemented entirely client-side, the server side stuff just syncs the behavior of multiple client apps.

Can you explain how? As the only way I can see this is if you did 50 different API requests for all 50 subreddits, merged the results, and then sorted them again by the desired order.

Why does the concept of a multi-reddit need to extend outside of the user’s instance?

it doesn't need to. But why would you not want it when communities are multi-instance?

perhaps I made a mistake introducing the privacy concern first. As now the whole topic seems to negate the very reason so many people have requested MultiReddit on Lemmy. The privacy issue isn't even essential, I just wanted to have a discussion about it as a general topic. I'm already building the code so that it can be done entirely without anyone sharing their personal subscribed list.

report a bug to lemmy about the broken quoting.

I have, weeks ago.

Consider posting to the official rust playground and creating a shared link.

I did share a link to GitHub, is that not good enough or something? Here is a screen shot for you.

Most common cause is people changing their language settings in their profile. It's a daily occurrence. The app really needs to tell people "25 messages not displayed because you are only viewing in Spanish".

Recently I’ve noticed my feed has become almost entirely the main meme instance. The algorithm gives me 4 meme posts then a technology post then load more memes

Yes, same issue, and I'm using lemmy-ui...

Lemmy's backend Top/Active/Hot are pretty primitive. I'm experimenting with some ways to weigh smaller less-popular communities... because +20 vote on meme topics is noise, but +20 on some focused community can be a big deal. hot_rank doesn't take that into account and just looks at published date and score. It's pretty tricky to get new things into the backend, so it may be a while.

I personally would need to dig into testing and code again to give answers with confidence. What I'm trying to say more than anything is... don't assume. The level of mistakes in Lemmy's more technical back-end code are pretty high from my experience, especially when it comes to multiple servers involved (comment deletes not being sent to all servers was a situation I tracked down). What I do know is that there is very little written out there about people actually tearing it apart and showing what works... a lot of stuff gets logged in server logs as errors that almost nobody can explain. Either it's mistakes in apub JSON or other non-lemmy servers, or older versions of Lemmy, etc.

When you say packages get forwarded to whatever instance wanted (if I understand correctly) you don’t “unpack” (e.g check if it’s a valid request)

the pack metaphor isn't that great. But it is signed, and the receiving server checks a signature. But I really have not seen anyone discuss how those signatures are exchanged in the first place, and I've seen people say they re-installed their entire instance - which I assume generates a new set of signing keys for the same domain name.... and I know Lemmy starts with 1 in index for post, comment, person - and would end up generating the same numbers for different content.

I haven't seen much eye towards auditing any of this works, and if it even is a good design. Even 2 months ago there were some aggressive timeouts that were causing delivery to fail. And when something fails, the person who comments or posts doesn't get notified....

There is some deep stuff in lemmy., every community has a private key/public key pair, as does each person - but I'm not even sure that is used at all and was an ambition. I rarely see the topic actually come up and I've been listening for this kind of deeper technical topics... and created !lemmyfederation@lemmy.ml to try and better organize it.

Thanks again, and sorry for the ramblings.

I'm pretty much rambling myself... my repeat point is: don't assume. I would not describe Lemmy as battle-hardened against attacks or spoofing that someone can find to bypass the current logic.

Like normal people! :D Go to another instance, if you find something interesting

So "normal people" would go read another instance just to bring a single comment or post over. They may as just well join the other instance. Which is what I see actually happening.... Many of these lemmy accounts are the same person duplicated to route around crashes.

But it’s a little bit sad, that you’ve never done this and only look at all.

If you had any clue what I have been personally doing with lemmy for the past 90 days, you would laugh at yourself. I've been logging in to several different Lemmy servers every single day for months and posting about my observations... such as when a big instance put new user interfaces online, upgrade their backend, crash on their home page, etc.

Having worked with lemmy_server code for months, I wouldn't trust it in practice. Unless someone produces a pretty through test to validate that it actually works as intended when out-of-band data delivery attempts are made. And for discussion sake, I am assuming comment and posting "messages", and not private messages... which is a whole different set of behaviors.

when a user homed on lemm.ee comments on a post where the community is hosted on lemmy.world, it would get delivered to lemmy.ml by lemmy.world, not the origin lemm.ee instance.

Messages are sent with a digital signature that only the original instance could craft.

I don't think the actual message carries a signature from the origin instance, in this case lemm.ee - I could be wrong, because it may not unpack and repackage it before forwarding to subscribed instance servers. But there are some very short timeouts on these signatures and HTTP connections, and I think it does unpackage it and repackage a public comment message.

I think lemmy.ml would need to go fetch the profile for the then unknown user to be able to get the display name and other details of the lemm.ee comment creator to display on the comment. The signature for the comment I think would actually only validate lemmy.world to lemmy.ml - and if lemmy.ml already has the profile of the lemm.ee user stored locally it may not verify it (and could be an entirely different install with the same username). But I don't think many have ventured into study the code in these areas. The whole process hasn't been examined that much and I wouldn't be surprised at all if there are issues with post and comment getting dropped because servers aren't all reachable at the right times for these steps.

How exactly do I deactivate the “All Feed” to not pollute my server and avoid distractions to the users, but let them comment on external posts

How would they ever find the external posts to comment on in the first place?

Personally I think the issue is more that there is blind loyalty to team sports in USA culture, and no matter how many bad things are documented about a specific person (Donald Trump, Richard Nixon)... people are loyal to the image of that person, the brand and logo. People are raised in the USA to be inundated with breakfast cereal and toy company logo/brand recognition. It's a faith system. Breakfast cereals and fast-food "Happy plates" that fund a lot of children's TV are incredibly unhealthy and profit machines - and parents think this is psychologically healthy.
