The straw man of my personal information isn't really relevant, seeking a more open government in order to have a more informed citizenry and better functioning democracy with real participation is a bit different than the personal information of one person. A better example might be privileged admin information that I asked not be shared...
Dread - having knowledge of the secret and illegal program of kidnapping, torture, and rendition run by the CIA might have made a difference and given the people a chance to object or make an informed judgment about the er. Doesn't the government still deny the program exists, despite all the information about it? The system is working, LMFAO!
Also - wikileaks has put out less than 1/2 of 1% of the state department cables so far. They have only released documents which have been reviewed by media organizations (they wanted review by the US government by gov refused) and redacted the documents per the orgs recommendations.
