Machine-assisted methods and apparatus are described for allowing individual users to develop and organize respective activity descriptions and supporting journal items according to their respective preferences. Cross-referencing mappings may be created between activity descriptions and journal items in order to find, filter and organize disparate data. Cross-referencing mappings may also be created between the developed activity descriptions of different users so they can better understand each others perspectives and possibly overlapping goals. Different users' activity descriptions can be presented to a user even while the user may be disconnected from communication networks. Hierarchical relationships between activity descriptions may be provided. Machine-assisted means may be provided for creating work-sharing, work-delegating and/or informational sharing agreements between different users. Further machine-implemented means may be provided for automatically and asynchronously updating users on shared activities by other users even though all users are not necessarily connected to one or more respective communication networks at same time.
