Care to point out the core flaws?

As far as I'm concerned there aren't any core issues. There are a lot of queries to a single DB which is one the same server, but there's nothing preventing you from running the DB on another server and sharding it if need be. I wouldn't call that a core architectural issue because the way you set up your DB is not core to the architecture.

It’s a federated system without any of the affordances that would make it usable (or particularly interesting to me). Literally load balancing by going to a long list of alternate instances. The sites own documentation just says, find one that works, and if that shits the bed find another. This is a UX agreeable to a very tiny and idiosyncratic group (as evidenced by Mastodon once the Elon is evil hype died.

Yes of course in theory you can beef up any instance, and shard, and add a caching and queueing layer while you’re at it. And tada you’ve just redid Reddit.

Sharding, caching and queuing doesn't break federation. That's not a core flaw.

As the ecosystem grows, a shortlist of popular, robust, federated instances will crop up for people who just don't want to bother.

Again, if you have any core flaws, I'm all ears.

I didn’t say it did, but it doesn’t enhance it either.

How short is a shortlist? When does that mean just new Reddit?

I suppose I would be more enthused if at the least the basic design eased standing up high traffic (or let’s be honest even mild traffic) instances. The performance story right now is: it’s written in rust - which is not nothing but it would be more interesting if supporting even a moderate amount of traffic on minimal hardware was an architectural priority. The flaw as I see it is that this is just not a design goal.

You can argue that things can be improved but initially well engineered systems help to enhance initial mindshare.

Even just two-three large and popular instances is enough to make a Reddit impossible, so that's how short it can get.

The performance story isn't just that the backend is written in Rust. It's also that the front is very lightweight (80kB), that the architecture is horizontally scalable, etc...

I don't see in any of those links a core flaw, a problem in the initial engineering that makes it impossible for the architecture to scale. All I see are some poorly written queries, for which the main devs made a root cause analysis and described how it can be fixed. Is that evidence that the inherent design isn't capable of adequate performance? No, it isn't. It's evidence that there are some small performance gotchas that can be fixed easily, and this is normal for an ambitious project.

But even as it is, yes, it can handle mild traffic. lemmy.ml runs on potato hardware, hexbear.net is an example of an instance which has ~3'000 comments a day, which is roughly the scale of this website, and it runs fine on a single dedicated server.

I dunno maybe I’m wrong about the technical stuff. My minor point is that this software has some technical flaws today - forums and link aggregators are solved problems over and over again so implementation excellence is at least a unique value proposition.

I’ll quote the top-voted thread here

>> Nobody wants a federated, slow, difficult to use version of reddit. Nobody wants to choose a server.

> I want this. I want this because it's a sustainable way to have Reddit without the ads. The bad UX is an acceptable tradeoff for a platform that doesn't go to shit.

I’m just not buying how a federated system of isolated instances solves this. What fundamentally prevents the dominant oligopoly or monopoly server(s) from just being Reddit running on Lemmy? Lemmy doesn’t dictate how things are run - so why won’t a major funded instance just evolve to a new Reddit? How does Lemmy decisively get you to a Reddit without the ads? What stops a major Lemmy instance going to shit?

Just having federation as an opt in feature doesn’t force the system to evolve in a particular way.

If a “Voat” equivalent pops up it’s not like the dominant instances are going to federate with it.

A federated system of isolated instances doesn't solve it, because that's not a federated system. The point of federation is that the instances aren't isolated, and they're highly interchangeable. No major instance has the incentive to become a new Reddit, because it's so easy to switch instances at every level that they just don't have the moat to make that happen. It's exactly the same thing as an email provider going to shit, but even less problematic.

If a Voat instance pops up, sure, dominant instances won't federate with it. That's perfectly fine. It doesn't mean that the inter-federated dominant instances can get away with pulling a Reddit.

Federation is an opt-in feature in theory, but in practice, what's the value proposition for an instance to turn off federation today?

It's really quite simple. Without federation, there is an incentive to pull a Reddit. With federation, there is no longer an incentive to do so, because you don't have a moat. What do you think would happen if Reddit only had 1/2 of the subreddits anyone used and if you could keep access to all the same communities on a competitor?
