A reader-centred approach has lots of advantages.  It allows people with different preferences in reading to talk to each other on common ground.   It cuts across the boxes that people tend to put their reading into, for example, highbrow/lowbrow, poetry/fiction, this genre/not that genre, classic/contemporary.

It makes no assumptions about what people have already read or about their knowledge of literary theory, the canon of great literature, or who said what in last Sunday's papers.  No special language is required because the reader-centred approach doesn't expect you to deconstruct, analyse, criticise or review what you have read.  It simply asks you to express what the book made you think and feel in your own words and on your own terms.  This makes the approach inclusive and non-intimidating.
