Today I spent some time looking at #comments4kids on twitter and found one students' blog that had no comments on it.  I know how awesome it is to go onto your blog to see that you have comments on your post so I thought that student would benefit from a comment.  #comments4kids is a pretty awesome thing on twitter, I think it is going to help a lot of students.  Many of the blogs I came across today said things like they only welcomed positive or helpful comments.  I think that's very helpful for the students creating these blogs, this acts like an awesome learning project for them.  This is definitely something I would be interested in doing with my own students when I get a classroom!
