I'd like to move away from Reddit, but I don't see any viable place to go. The best thing about Reddit is how generally casual the user base is. It's not just a self-selected number of tech-affine users. It's people who love books, people who love running, or video games, or space, or literature, or knitting, or anything and everything else.

Reddit has centralized what would otherwise be hundreds (thousands?) of obscure, splintered and isolated communities and forums. What could possibly compete with that without having already reached critical mass and become an obvious competitor to Reddit?
