Everyone who needs it has to build their own personal knowledge management system. Usually a set of ad-hoc unwritten rules of how to manage an organic collection of documents, journals, to-dos, project notes, computers, servers, services, applications, protocols. I have not seen any single solution that solves the full range of needs, probably because the way a person thinks, remembers, and learns, is so personal and different from each other. (Or is it? Perhaps we just haven't found the right universal conceptual framework.)
