A couple of interesting Twilight pieces:
No Twilight for Reading at The Book Whisperer. Donalyn Miller says, "If we want to encourage students to read, we must validate some of their less-than highbrow reading choices when they do. Hopefully, due to the popularity of event-books like Harry Potter and Twilight, this generation sees reading as part of their culture—right alongside Guitar Hero and Facebook."
I thought the "event-book" comment was particularly thought provoking.
What Girls Want by Caitlin Flanagan in The Atlantic. I can't say I read all this one. This is one of those "reading and me" kinds of personal essays, in which the essayist brings in all kinds of material about herself while discussing her reading. If David Sedaris or Sarah Vowell had written it, maybe I'd have been more interested. The essay's main claim to fame on my listserv is this line: "I hate Y.A. novels; they bore me." But all essays about and reviews of YA in mainstream, what you might call popular adult magazines include some variation on that.
The author, Caitlin Flanagan, has a bit of a reputation for being outrageous, anyway. Metaphorically speaking, she's kind of like Ann Coulter's more coherent sister, the one who got married and had kids after college instead of going on to law school and hanging out making jokes about politics with the guys.
