Because information horizons consist of a variety of information resources, including social
networks, documents, information retrieval tools and experimentation and observation in the
world, many of which have some knowledge of each other, perhaps, information horizons may
be conceptualized as densely populated space. In a densely-populated solution space, many
solutions are assumed, and the information retrieval problem expands from determining the
most efficient path to the best solution, to determining how to make possible solutions visible --
to an individual(s) and to other information resources.
