The great fault in the linked article, with which I do agree with everyone, is that folk "should" feel embarrassed to read YA. Heck, people should read whatever they darn well like and damn the looks on the bus. I'm sure there must be plenty of enjoyable YA novels out there, and good luck to all who wish enjoy them.
However...
I do have some sympathy with the article from the standpoint that I just don't get why adults would read this stuff. YA books are aimed at teenagers. I am an adult. I've never felt the least wish to look at a book aimed at kids since I was one. There are sooooooo many good books written for adults which are neither "overrated literary stuff or badly written potboilers" that if I lived to be 200 I'd never get through 10% of my mental adult tbr pile. I know readers of YA books will say I shouldn't write them off and so-and-so book is wonderful, etc, but from a personal standpoint I'm just not interested and I'm mystified why other readers are.
