Blown to bits Chapter 3 Summary

In this chapter of blown to bits I learned that there is many hidden information in many documents in a computer. It pretty much says in the chapter how this can affect us in many ways, due to which kind of information is stored in the computer and the documents. Of course it might not always affect us in a bad way, it can sometimes help us with other things that will only benefit us too but that also depends what kind of documents you have stored in that certain computer.  Companies apparently have made mistakes with the information hidden in the documents, and the chapter explains some examples these companies made. It is important to be smart and keep every document safe.
