"While you’re logged onto Facebook, for instance, the network can see virtually every other website you visit. Even when you’re logged off, Facebook knows much of your browsing: It’s alerted every time you load a page with a “Like” or “share” button, or an advertisement sourced from its Atlas network." If you want to enable sharing of your content on FB and other platforms easily but you do not want to support the tracking madness, you might want to use Shariff. It's setup to not send any tracking information to FB etc unless the user wants to share something. https://github.com/heiseonline/shariff https://github.com/heiseonline/shariff
