Is there something that SO can do to further segment the site and/or the question pool without making it too hard to use or driving too many questions into total invisibility? The problem with SO as I see it is that every question is part of the same pool of questions, only differentiated by topic tags. Every question is held to the same standards. This is a contrast to the actual people who use the site: askers and answerers are all using, looking for and expecting a huge variety of different approaches and responses, and have wildly varying levels of experience. Reddit's subreddits completely transforms the site for people who use them - people who browse the front-page have an entirely different experience and different expectations from those who curate. I wonder if there's something similar SO can do.
