Weekend Review

I have learned what a discourse community is this week. I still don't know exactly what is the difference from a discourse communtiy and an audience though. I think all the things the faigley talked about regarding a discourse community is implied when you are thinking about what type of audience you are writing for. I think Faigley just wanted a book to publish because the ideas he presented are not nearly as revolutionary as he woud like to think. One question I have would be - What does a Dicourse Community have that an Audience truely doesn't?
