Everyone convincing each other in the comments that nobody cares about this is clearly wrong, and are being so in an insanely toxic and dismissive manner.

So when people vote according to what you prefer, it's validation of the problem. When they don't, it's "insanely toxic and dismissive". Surely you see the problem with this line of argument?

Who gives a shit about user experience anyways?

This is a type of "faster horse" case. The fact that so many people are asking for it is just an indication that they are stuck in "centralized system" mentality, not that they are facing a real problem.

there are many communities that died due to lack of traction.

Can you give actual examples where the community died because the people were splintered around? Because from the majority of communities that I see that are dead, they are dead simply for a lack of interest from the people, or the creator just wanted created a quick replica from reddit but never worried about cultivating it.

To illustrate: the Nix community even created a Lemmy instance and announced on Reddit, but it ended up completely dead because the most experienced people ignored are already on Discourse. The newbies here on the Fediverse wanting help knew were to go, but were posting questions and receiving crickets in return. Of course it would die.

Also, something similar to less popular programming languages. I was doing my best to help !elixir@programming.dev to come off the ground, but there simply isn't enough people interested.

What would help is that people stopped trying to find a "canonical place" to put content and just went on to put content without much worry. I have been basically posting on !humanscale@communick.news by myself. Would it be nice if more people posted? Yes. Do you think I will just give up because it's been six months and no one else cared to post there? Of course not.
