Rip, Mix, Learn Playground

I looked over the sites to do with English classes, and noticed that most of the day's postings were about how hectic the students' lives were and how hard it was to keep up with classwork and how many hours they were working at their part-time jobs. like teacher-endorsed MSN. But I scrolled down and found the on-topic postings - discussions of Shakespeare, interpretations of novels, etc. It was impressive. i can really see this working for a group of students I have who love to read and will discuss their reading spontaneously, but not necessarily broadly. I would like to see applications to literature circles. Did anyone see a site on this?
