For context I use all of these daily: Linux (servers + handheld gaming), Windows (gaming), Mac OS (work & general purpose). I used one of the first iPhones around 2008, then exclusively Android for 10 years, and then back to iPhones.
Iphone users of Lemmy, people say not to trust you on tech insights.
IMO, these "people" with such takes are the only ones who shouldn't be trusted on tech insights here :P
The sad fact is that some people keep constantly spreading false rumors about Lemmy devs not working on mod tools. Anybody can just take a few minutes and go through the past Lemmy updates in this community to see that moderation improvements are basically worked on constantly (and this is not some recent change either). But there are plenty of users who never bother to actually check this, and so the rumors keep spreading.
This "ads as posts" thing was one of my two biggest concerns with Threads federation. I really hoped I would turn out to be wrong about it, but at the end of the day, both Facebook itself, as well as big social media influencers, rely on advertising for their profits. For anybody looking to avoid ads on Lemmy, it seems like direct federation with Threads is not a good idea currently. On lemm.ee, "no advertising" has been one of our 4 core instance rules from the start.
My other major concern was Threads having the ability to enforce their feed algorithms on federated instances through sheer number of votes on things they show in their feeds, but judging by what you're saying about the engagement, at least that concern has not materialized (at least yet).
I think community discovery can (and should) be improved for sure!
Currently it's true that you can use topic-centered instances for this, I do this myself as well, but I do think it has quite significant downsides in terms of creating pockets of centralization. For example, if you're a user who is ONLY interested in french cinema (or any specific topic) on Lemmy, and all of the related communities and other invested users are on a single instance, then for you, the experience is absolutely no different from any centralized platform - the french cinema instance admins have 100% control over your Lemmy experience.
IMO, in practical terms, 3 key things should imapct instance choice:
Basic instance rules (including things like community creation policy, nsfw allowed, etc)
Federation policy
Instance infrastructure (hardware & how it's managed)
Content specialization really shouldn't matter IMO, because as long as the federation policy is OK for you, then you can participate in any communities, regardless of what instance they are on. In other words, even if you're super interested in french cinema, there is no need to centralize all users interested in this topic on a single french cinema instance. Thanks to federation, users from all instances (accounting for federation policy) should be able to become fully fledged participants in any french cinema communities.
Of the points I listed above, #1 and #2 are easier to include in an instance introduction, I'm not sure how to properly and reliably reflect #3 in any kind of overview. At the end of the day, I think most users tend to figure out their long-term home instance a while after they first join Lemmy, and quite often, it's not their original instance, so maybe it's not that important to emphasize the initial instance choice too much?
Admins still get (and look at) reports even from communities without mods. In the past, if such a community has started causing issues, then I have closed it down, but based on a lack of reports, I don't think there's any issue right now with either of those communities.
By the way, anybody is welcome to take over communities with inactive (or missing) mods on lemm.ee - just drop me a message and I'll be happy to transfer the community.
If I have several backends that more or less depend on each other anyway (for example: Lemmy + pict-rs), then I will create separate databases for them within a single postgres - reason being, if something bad happens to the database for one of them, then it affects the other one as well anyway, so there isn't much to gain from isolating the databases.
Conversely, for completely unrelated services, I will always set up separate postgres instances, for full isolation.
Sorry about that! It's a mitigation we have in place which has helped protect against several attacks so far, but unfortunately it has the trade-off of sometimes hurting normal users. Are you browsing with a VPN or Tor?
The goal is to make it completely possible for anybody to use as a full replacement for the lemmy-ui if they wish, but I think including it as a the UI for the "default" Lemmy setup is not going to happen. Not that I would have anything against it, but I mean, lemmy-ui is still completely functional, and lemmy-ui-leptos probably isn't too far off either at this point.
The built-in search feature is actually quite decent I find, is it not working well for you?
