This document discusses conceptualizing Web 2.0 from a social perspective rather than a technological one. It argues that users play a more active role in producing Web 2.0 than the underlying technology implies. To understand this, it proposes looking at Web 2.0 through the lens of affordance theory and as a "container technology" that allows users to realize interactive potential through contextualized use. Taking this approach views Web 2.0 as configurations of social, spatial and temporal relationships defined by users, rather than technological rules.
