Sure ... but 99 out of 100 users just say "weird" and leave. And that's "How Quora died".
I'm not here to defend Quora, but my speculation is that Google's preference for long-form content is equally to blame. Basically the same reason as recipes that start with a long life story: Google prefers pages with lots of content, even if 10% of it is actually useful to anyone. So a page with 50+ "answers" is preferable to a page with two actual answers.
But the best results are those where the user uses the back button and clicks something else. They must not click back within n seconds of course. The user has to spend a minimum amount of time on the almost useless page.
I got this feeling looking for many things. I know there are pages but get many results very very close to what I was looking for.

Then people start making perfect SEO pages like "how to style css with html"
