I think that this idea is stellar! I like it the most for three main reasons. First, the reading circles are beneficial to all with very little effort. They are self sustaining as long as there are books to read and readers. Finally, they build upon established values within the groups and cultures so there is little opposition in implementation.
I was also reading some of the comments, and I love the idea of a writing contest! It gets the kids involved on a higher level. I wonder, would it be possible to take this a step further in camps with high participation rates by encouraging listeners to have regular"book clubs" or discussions of the books that they read? This would encourage listeners to read more and take steps on their own- hopefully creating a group that could stand on it's own with little effort.
