Publisher's Weekly has two reports of interest:
Kids' publishers panel
This post includes an interesting discussion about publishing formats and prices. I particularly like this quote from Jann Jones of DC, who is heading up the new kids' line, noting that many of the creators formerly working on kids' books would rather have been working on books for grown-ups: “They would just write watered-down versions of our characters,” she said. “I wanted something just for kids by people who were passionate about it.”
A short report on the panel about comics for girls, with title recommendations.
Jimmy Gownley, kids' comics superhero, speaks out: Gownley was quick to respond to a complaint that comics were “dumbed down,” noting that because the pictures help guide comprehension, a child can read a full grade higher in comic books than in prose.
