How can educational blogs be used?

This year I will be using a blog to log every time that our curriculum calls for technology that our campus does not have. We have cried and cried for more technology due to the curriculum that we are currently using. The principal said that the only way we can be heard is if we document every time we do not have the right technology. We as a department are going to log every time the lessons call for something that we do not have. I am hoping that this will lead to our department getting more technology.
