This is a great story about an 9 year old girl who decided that she wanted to see some changes in the quality of food that she was getting at her school. And how can a 9 year old do that? She started a blog, and shared photo's of the meals. The local authority didn't like it, and they banned her from doing it.

I think this story is a fantastic example of how technology enables a freedom of speech often not afforded to students, and how community support can bring about change. 

If nothing else it a good example of positive use of technology by young people. It well worth a read.
