Too Old for YA?

It's time someone discussed this non-rationally.

I want to know what you think. Do you prefer YA books written by people in their 20's? 30's? 40's? Do you see a trend in your favorite books? Or is it just the book you see?

I'm 46. There. I'm out.
But I'm finding the YA and middle grade genres are crackling out of my fingertips--with lightening, not because my fingers are crumbling. It's probably because of my adolescent-stuck brain or the fact that I've raised four boys and a diva and therefore have plenty of content. But the question remains, will young readers want books written by somebody's grandma, or will they give a rat's butt?

What about you? Peek at bios much? Of course YOU do. But do you suppose the young readers do? POST A COMMENT AND YOU WIN...NOTHING
