Brian Kennish created a new Chrome plugin:
>Facebook Disconnect blocks all traffic from third-party sites to Facebook servers, but still lets you access Facebook itself.
I’d say that is a must have for any Facebook user.
UPDATE: [This plugin](https://chrome.google.com/webstore/detail/jeoacafpbcihiomhlakheieifhpjdfeo) is a bit more robust in blocking many other services.
