People who haven't gotten into habit of googling stuff in the last 20 years might not get into it at all anymore because of how search engines are gamed with SEO spam tactics nowadays
If it could be done, and done right, I'd love to see a couple wiki-like additions to the fediverse, one focused on products and product-specific information and care, with the other focused on the development of a catalogue of methodologies and tech for production and more general repair. Not tech news like the technology instances I'm aware of.
But I guess it's not suited for the format, nor could we really hope for the task of building anything even close to exhaustive to be a surmountable one for us.
I had some ideas about UI/UX for something like this a while ago, though it wouldn't work with Lemmy. I could probably find my notes and sketches, but effectively they're just a bunch of wishful thinking born from my dissatisfaction with the limitations of Wikipedia, the chaos of Google, Youtube, and Reddit, and the ridiculousness that is WikiHow.
It's been a few years tbat I've been crossing my fingers for a positive paradigm shift specifically for the online content about products and DIY.
There might be some kind of trust system that could work. I have no idea of course but I'm envisioning something like Stack Overflow's system and a bit of community correction and authority à la Wikipedia.
