Use this Stack to create some privacy in this world of social media. Facebook, Google and Twitter's plugins are communicating to their servers as soon as you enter a website. You normally don't need to click on a button in order to give them knowledge about your way through the internet.
Social Privacy uses placeholders on a first step. There's no communication with those social media servers unless you explicitely click on one of the placeholders which will dynamically load the corresponding plugin and enable the communication.
As a second step you can now click on the loaded social media plugins as you are used to know it...
