For Semantic Synchrony[1], we keep our notes in Semantic Synchrony, a knowledge graph server (written in Java, using Gremlin and Neo4j) and client (Emacs). It allows for selective sharing, and you can connect your private notes to your shared notes however you like -- for instance, I've got a lot of "half-formed hypothesis" notes that I don't think are worth anybody else's time, so I keep those private. It eliminates the dead link problem, and the linearity constraints that trees (let alone flat folders or text files) impose. It's open-source, with a lot of features, and well documented.
