Power is in the individual person who has access to any-form of connection to the Internet. I believe that whistleblowers as WikiLeaks is only the beginning of a numbers of leaks that will have different names as OpenLeaks.org.
We will see copy cats of Günter Wallraff, working as employes but later leak information if they feel it is the only way to change the way business is done.
A whistleblower is a person who raises a concern about alleged wrongdoing occurring in an organization or body of people. Usually this person would be from that same organization.
Never before has the grass rots been so powerful.
