search history is useful. google should provide me "query suggestion" based on my social circle. without collecting user data, google,/FB etc can't exist, they can't improve their services. As a user, I don't care much on the data they collect, as long as they follow law system in the country they operate. if these huge companies went beyond the control of the governments, then only the real problem starts.
