Teen Chick & Lad Lit

An excellent comment to the previous post from "Steve." (Note to "Steve" - I said "emergent" genre: you read it as "emerging," I think?)

I think the existence of these 97 titles, currently in print would qualify it as a genre.
Also, I get the feeling The Babysitter's Club and Sweet Valley High would count as teen chick lit -- at least these are what my sister was reading when she was in her early teens. On the other hand, there are not a lot of lit geared towards young boys -- I suppose it is hard enough to get boys away from their computers, TVs, and X-Boxes, let alone convince them to read a novel.
I know Harry Potter has dramatically improved young readership, but I wonder what boys think about reading books written by a woman? Do they think about it? I used to love reading Judy Blume novels, but I think I had some qualms about it nonetheless.
