When doing such searches I don't actually want Reddit specifically, my real goal is just to find information that is (supposedly) from a human discussion between individuals, as opposed to conclusory "articles" or "best of 20XX" or "top 10" etc.
In other words, I don't want Google to elevate Reddit, I want them to classify site-types and allow me to filter results for "forums", which would include the long-tail of less-known smaller places.
