I've been thinking about a reddit like site where the communities are organized categorically using a btree like structure. Posts bubble up through the tree as they get more attention. Filtering would be easy. Don't like cooking? Clip that subtree. Only want nsfw? Make that subtree your root. Did you recently find Stargate SG1 and want to know what other kind of sci-fi is out there? Check /t/tv/sci-fi and see what else is popular. It would be tough making sure subtrees are categorized correctly. Modding would also be tough since parents probably need ways to block children but that feature can be abused. Many topics should have multiple parents which would complicate things some. Maybe internally everything is a single graph that's represented as a tree visually for users. I guess there's plenty left to think through but it would be a cool experiment.
