This entry really describes my relationship with reading only in much more fluent and lyrical language than I could ever use. Check it out.
I have heard Lois McMaster Bujold talk about, and read her thoughts about, the author/reader relationship too and thought her ideas were also very insightful. I just wish I could remember where I read it!
I agree with both.
Successful readers must have active participation in what they are reading. The author puts the words on the paper and they mean something to them. The reader reads the words and they mean something to them. The somethings aren't always the same or even similar. It is part of the wonder of reading for me.
