There are a lot of small websites on the Internet: Interesting websites, beautiful websites, unique websites.
Unfortunately they are incredibly hard to find. You cannot find them on Google or Reddit, and while you can stumble onto them with my search engine, it is not in a very directed fashion.
It is an unfortunate state of affairs. Even if you do not particularly care for becoming the next big thing, it’s still discouraging to put work into a website and get next to no traffic beyond the usual bots.
Vast, vast majority of sites that exist are small. And significant portion, if not most of them are going to be actually not that interesting or outright junk. Who’s going to decide which are good enough to show up on the list? And how are you going to maintain them over time—if you succeed in making a small site discoverable, now what, is it going to be on the list forever? If not, on what kind of criteria you’re going to maintain it, and how are you going to measure it?
Don’t get me wrong, I’m not saying people should built these lists, they absolutely should. But there is no one-size-fits-all solution and creating something that resembles one-size-fits-all is going back to the twisted, weird system that so many of Lemmy users (including me) are happy to be away from.
I see no problems with the screenshot you posted. Of course that “KIA” comment is extremely insensitive at best, but we all know that any sort of open Internet community has this problem.
If you find Reddit more interesting, then you have already solved the problem for you: just go discover things there. If you find your Lemmy homepage boring, maybe sub to different communities and set up your page to show subscribed only (that particular setting helped me a lot).
If you want to create some sort of smart automated strategies that get you to have the the cake and eat it too (eg. remain subscribed to all of those communities but filter posts for based on some sort of diversity criteria eg. “no star trek more than once a month”) then please go ahead and experiment: the content is freely available using computer-readable formats, you can learn to code or hire someone… I bet someone is already doing something like that. You don’t need to solve the problem on higher level, and doing so is going to do more harm than good.
But as you say, it’s not an easy problem but I think it shouldn’t be. No individual should be able to impose restrictions like that globally. We are each responsible for our own diet. (And for lemmy.world thank mods for keeping out the shit sprayers.)
I love the fact that federation means we could have a grandma-focused instance that applies all my hypothetical filters by default. It’s possible… but there is currently no desire to become the front page of the internet. We’re a niche, and that just means we aren’t the place to try to advertise for the little guy.
