Wiki's in the Classroom

Thanks to another member of my Commerce cohort, I recently learned that we can easily create Blogs and Wiki's on our blackboard accounts for my students to use in the classroom and at home. I have been contemplating about having my students create a wiki based on their literature circle assignments. I was wondering if anyone had any experience using a Wiki in their lower elementary classroom? I was thinking it might be interesting to create a schedule for my students in which they had to post about their reading group's setting, characters, and predictions. This would help them to build on each other's thoughts to create a detailed analysis of their literature reading. I was hoping this would solve the problem of my reading group dilema. I have too many students to work with everyday during reading instruction. Therefore, I wanted to try and find a way to incorporate either Blogs or Wiki's during this time as the majority of my students do not have computers at their homes. Does anyone have any helpful thoughts or ideas?
