At the end of the last century the web was conceived of as a
library where information could be posted and retrieved, so that
there was a fairly clear distinction between the roles of producers
and consumers of information. Since then what is called Web 2.0
has emerged as a highly interactive space where all participants
are both producers and consumers. Intensive users of the virtual
space find that it has changed the nature of their existence in the
‘non-virtual’ world. In this volume we look at the linguistic and
discoursal complexities of interaction in the virtual space in relation
to events and discourses outside it.
