“…But there are forms of synchronous messaging or internet relay chat in which participants are online at the same time and contribute to a 'live' unfolding discussion. Texting falls somewhere between these types, since participants may retrieve texts sent to them at any time, but in many instances texters engage in synchronous exchanges of messages and replies (Hutchby and Tanna, 2008;Laursen, 2005;Weilenmann, 2003). Interaction in such environments is better characterised as quasi-synchronous, however, since the technological mediation introduces a temporal lag between turn production and reception which renders turn-taking problematic; or at least very different from ordinary conversation.…”
