Although this paper was a good read I do feel that it took an awfully long time to say not a lot.

Reading the paper did improve my understanding of sequential and cultural contexts in speech utterances and the importance of considering these when analysing dialogues.

Understanding the relationships between conversation participants helps understand the conversation through analysing the dialogue - are the participants on an equal footing or does one have some sort of superiority over another? This would change the giving and receiving of an utterance.

From the paper:-

 There is no point looking at a single utterance without considering their place in the local sequence of utterances and there is no point just looking at their sequential place if the contextual details are available. Contextual knowledge is a luxury though

 The analyst must know the cultural as well as the sequential rules for the use of certain utterances to correctly analyse the dialogue
