Connecting back to the ideas of audience and genre, on page 212, Schryer, while referencing "Bakhtin's most important insight" says "The change in speaking subjects determines the boundaries of the genre."
Here he is speaking about audiences and their direct connection to genre. I too find this an interesting point in that genre is created by humans and that the humans that a piece of writing is intended for can dictate "the boundaries" of that genre. The audience determines the writing. Democracy in action.
This to me is the central issue of this study. One of the problems that this article is seeking to address is that the students of this college were not communicating their own records very well. Their notes and writing were written for an audience of one (themselves) with no real thought as to who may need to read this information in the future.
Their records and research which when presented for multiple audiences could be a part of a larger discussion, much like this one, are instead left out. To me this is a great disservice to the researchers in any field.
