Chick lit again

A blog post by Diane of Trashionista in todays Guardian seems to have created a heated response. I wonder why this genre seems to create a wider divide in opinion than almost any other? There is absolutely nothing wrong with books which are designed to entertain...indeed one of my more educational experiences as a reader was picking up a copy of Jilly Cooper's Rivals in an airport in desperation, thinking I would hate it, then finding it to be a fantastic beach read. However, I think some of the commenters have also made very valid points. Why not have a look and see what you think?
