Based on the class discussion the most significant question that has risen from our reading is the relationship between the author and the reader in a text. Many would say that the author holds the power because they are producing the text and there for can mold it to fit a particular genre and audience. On the other hand there's the fact that the reader is the one interpreting the text and therefore truly holds the power because while the author is the encoder the reader is the decoder, and regardless of what the intended signal is, if it isn't received properly then it defeated the intended purpose.
Take a look at Facebook for example. Facebook is a social media channel where statuses are constantly being updated for the public to observe. while the poster may intend for the status to be read one way, it may be taken another--especially with sarcastic posts--and as a result cause an unnecessary uproar. The way the audience receives an intended message ultimately out ways what the author meant to say. This is especially true since we're often told in literature to factor out the author and to only focus on the text and its interpretation.
