content: What is the best way to block Twitter, Facebook, and other popular social media "telemetry" at the router. There was a good write up on how to block Google's analytics at the router. Is there a good source for finding this for Twitter and Facebook et al? If so how do you verify the information? I bring this up because twitter links are creating a heavy footprint on the front page and I keep clicking on the links (like the old idiot I am).
