Every nugget of knowledge is relevant and useful. There is no knowledge that can be described as immaterial, irrelevant, unnecessary, or without potential use. Since knowledge advances and grows by means of cumulation, every nugget adds to the pool, like every brick which is an essential component of a wall. The only possible shortcoming of any nugget of knowledge is the extent to which the transactor or user of knowledge is able to cluster it with other nuggets in his possession. The fault in any knowledge not being considered relevant and useful is not in the knowledge itself, but in the transactor or the user (e.g., Card, 2000; Davenport & Volpel, 2001; Patriotta, 2003; Rajan, Lank, & Chapple, 1998).
