Knowledge consumption and knowledge creation are not separate but parallel processes, as knowledge is co-constructed, contextualized, cumulative, iterative, and recursive.
@clhendricksbc (above) is right that this is a key point. It brings out the Foucault in me, the way that discourse is a social process lodged in relationships of power. Maybe some of open's effect is to re/unbalance existing power relationships in the consumption and creation of knowledge.
