While I get that many people use FB, at its core it acts much like a Trojan Horse virus. Its main purpose is to gather and spread your information to as many people as possible, much of the time without you being any the wiser, tapping into every contact list you have and sharing what you read and or reply to with everyone on your friends list, whether you want it to or not. All of this is fine, if it's what you opt into but even with their ever changing updates to security settings, most don't know how little of their privacy is being protected.
