Facebook "like" Button

As you may know it´s possible to build the "like" button into your website or blog. It´s a great way to make the web more social. I build the "like" button into this blog as well. In the footer of every blogpost you can click it if you like the post. If you click (and you are logged in to your facebook account) it appears in your timeline and other facebook-friends who are interested in the same topic become aware of the blog or website you just liked.

As I learned today via @9elements in this article there is a potential downside to the button: If you don´t log out on facebook and keep moving through the web facebook would technically be able to track every site you watch as far as the site has the like button implemented as well. It won´t be long until the like button will be everywhere, because everyone who creates content would love to get facebook-traffic directed to his or her website/blog. So if you want to avoid being tracked everywhere log out of facebook before you continue. Just to be clear: I´m not sure if facebook actually does track the sites you visit (and probably nobody is) but it´s possible.
