The way I see it, ranking the web was the easy part but it has already started to become hard.
It's an old trope that search engine results were fantastic around 2010, but these days there's so much bloat and SEO to deal with that ranking is becoming intractable.
I miss the days of Youtube dislikes where you can instantly see whether a tutorial is going to be any help. I figure with decent moderation for bad actors, a system like this could definitely work. Take the success of Reddit / HN / StackOverflow as proof of it.
