Comments4Kids is an internet meme. The purpose is to identify student/class blogs that would benefit from comments done by others. I recently upgraded the site from Wikispaces to a blog, Comments4Kids. I would like for you to look at the site. Would you use this in your classroom? How would commenting help your students?
Also, check out the Student Blogging Challenge that is going on now. Here is a list of student blogs that are taking part in the challenge.
