Even if you publish nothing about yourself, information will leak. Some of your friends will post things about you... for example they have a photo together with you, will upload it to a social network, enter your name, provide a date and place for the photo... with enough photos with your name, the social network can make a guess about which other unnamed photos contain the same person... and gradually a profile on you is being built.
And it will only get worse, as more data will be shared by other people. Soon the streets may be full of people using cameras all day long, just because it allows them to make cooler diaries or blogs, and then the data companies will get universal surveillance.
The only way to keep privacy will be to have your face covered in public (but hey, that will be made illegal, because terrorism or something), or avoid public places completely.
