Lemmy.world is very popular, and one of the largest instances. They do a great job with moderation. There’s a lot of positives with lemmy.world

Recently, over the last month, federation issues have become more and more drastic. Some comments from lemmy.world take days, or never, synchronize with other instances.

The current incarnation of activity pub as implemented in Lemmy has rate issues with a very popular instance. So now lemmy.world is becoming a island. This is bad because it fractures the discussion, and encourages more centralization on Lemmy.world which actually weakens the ability of the federated universe to survive a single instance failing or just turning off.

For the time being, I encourage everyone to post to communities hosted on other instances so that the conversation can be consistently access by people across the entire Fediverse. I don’t think it’s necessary to move your user account, because your client will post to the host instance of a community when you make a comment in that community I believe.

    I realized the irony of posting this on unpopular opinions hosted on lemmy.world, which is actually demonstrating the issue!

    would be cool to link to current federation issues so people would actually see what’s happening and how vast the problem is. I’m sure someone must’ve already made a list

        For that example, there may be something else going on. The time behind graph for Lemmy World- > Hacker Talks seems to only average about 90 seconds. Some of the comments that show up on LW were made hours ago. If it were just federation delay, they should have arrived already.

        Assuming those are going straight to your Lemmy server and not to a proxy that buffers them? If you’ve got a federation proxy buffering those, then the graph would be off since it wouldn’t show what’s sitting queued in your buffer.

        You still definitely have a point. Every couple of weeks, my instance seems to start lagging behind by several hours and then goes back to normal after a few days. Still not sure why unless there’s just a huge uptick in activities being sent out from LW. I made a post about it yesterday, but it doesn’t dive too deep into the technical details; basically just an info post to let people on my instance know I’m aware and trying to do what I can about it.

          Good point. And thank you for the graph. It could be that the activity pub protocol is best effort, and if lemmyworld is overloaded, or just dropping packets, whatever activity was supposed to be sent at that moment gets lost forever. That would explain me divergence, and lack of eventual consistency

          But I only have data for missing posts from lemmy world, and only some communities.

          I don’t know the actual cause of the issue, but I think it is definitely related to the size of the instance. So from an empirical perspective the advice is still promote communities on non-mega instances

    Just like libertarianism would soon lead to single party Government, then eventually to Democracy, most people just want a less shit version or Reddit.

    This whole Federation thing is a good principal, but most people just wanted a less crappy version of Reddit.

      Most people may have just wanted a less crap version of Reddit, but how you make Reddit less crap is that you spread out the moderation and also don’t grow power in admins. That’s what federation (mostly) does. I just think we need a way to transfer a user and also to load multiple profiles.

      I also don’t understand why federation needs to be the way it is. I feel like instances could present a “read-only” version of themselves to defederated instances so that users could at least read the posts but not interact.

    Leave Lemmy.world for other reasons too.

    I’m still irritated that when I signed up last summer, it was like: it doesn’t matter which instance you choose because we’re all connected.

    It’s not true. Lemmy.world relies too much on banning communities and even entire instances. I am the one who should be entitled to make those decisions, not Lemmy.world.

    Consider coming to SDF Chatter or Lemmy.today instead.

      If the front end is a single website, then it can be taken down, and provides a central weak point.

      As a DevOps Architect, let me make it simple:

      With a single front-end, you have a bottleneck. If you have one domain (website) that everybody goes to to get to the front-end, that means that domain is the single point of failure.

      In my line of work, we use load balancers and sub-domains to divide the work and provide resilience (High Availability), but at the end of the day, if the DNS for that site goes down, we’re down.

      Also, as Jet mentioned, whomever whoever controls the domain (website) controls the content. You can’t have multiple groups controlling a single domain. Whomever buys it controls it. If they don’t like content, they could easily block access to it.

      I’m oversimplifying the inner workings, so if you want more details, let me know.

      EDIT: subtext called me out on my crap English. Have nobody to blame but myself. English is my first language.

        I just want to let you know that “whom” is only ever used as an object. In your sentences, I think you should have used “whoever”.

        The easiest way to remember which you should use is to think about the difference between s/he==who and her/him==whom.

        She gave the ball to him Who gave the ball to whom

        She controls the domain Who controls the domain

        The domain is controlled by him The domain is controlled by whom

      Decentralization should be a background thing with hosts providing server space like you would get from a service like AWS and the front end being a single website with users not knowing on which server their content is hosted and backed up.

      You could potentially run into issues with data storage reliability:

      • What happens if some server hoster were to simply delete their hosted data? Would the data simply just cease to exist? You would end up needing to duplicate it some amount of times to statistically ensure some level of security in the data, and, even then, it’s not a guarantee.
      • How do you ensure that the data doesn’t get tampered with when it is stored on other people’s untrusted servers? You would need some way to digitally sign data with a user key, which carries with it many potential catches.
      • You would need to make sure that the data, and networking needs, are distributed according to what the server is able to provide.

      I understand that these things could still happen, to a similar extent, with the current model of Lemmy, but they are less likely to occur, given that you can choose which instance to join. These are all not unsolvable issues, but this is not a simple “better” alternative — it’s more complicated than that.

      All this being said, there is a service that I have heard a little bit about that is sort of similiar to what you appear to be looking for called Nostr.

    I used to be on feddit but it shit the bed and the admin hasn’t been able to fix it for over a month.
    Before that I was on lemmy.ml but I was banned for speaking truth to China.

    Every time I add a new instance I gotta go in and block all the communities I don’t like all over again

    World was the first one where I got an account quickly without some weird application process. And now I can’t easily migrate.

    It took me 5 months of multiple attempts trying to get into Lemmy.

    I tried so many different instances.

    .world was the only instance that would let me in.

    can someone please explain to me why it’s so difficult to get into some instances?

    Why was world the only one I could get into?

      Huh. I saw some list when I was joining detailing different instances and why you might join them. There was zero issue when I picked the instance I’m on (lemmy.zip), but I’m not sure if that list still exists.
