I just started my 6th graders in our Wiki site during class today.  With only 7 students entered during class, they went home and chatted with over 65 comments back and forth to each other!  What a great way for quieter kids to connect with a social group!  We set up this wiki for our tech team to have a place to plan their upcoming cable access tv show.  I can easily monitor their comments and I hope these original 7 go back to school tomorrow and spread the word of how fun it is.
