Through child_lit (see info about the childlit listserv here), I became acquainted with Debby Dahl Edwardson. I subscribed to child_lit in 1995 or thereabouts. Sharing my perspective---one that challenges a lot of what gets published in children's books---I encountered a lot of resistance from people on child_lit.
Since then, there's more people on child_lit who are willing to challenge the status quo. Debby is one of them. I'm glad to see she's started a blog. Take a look, and bookmark her site.
