Today I checked out Lupine Seeds, Linda Crotta Brennan's blog. I've actually met Linda a few times. She writes a lot of nonfiction and has published an impressive list of shorter work in magazines.
At her blog she's recently done a number of author interviews--extensive in length and accompanied by photographs. She also does her own commentary on issues in children's literature. (Linda, those recommendations for authors to limit themselves to only a few hundred words for picture books are a mystery to me, given that I'm always seeing picture books with lengthy texts on subjects of interest to people in their thirties or forties.)
