It was four clicks for me to set up an email filter on Gmail in response to a message in my inbox.

And there's considerably more filtering options, had I wanted something non-trivial, than there are on FB or Twitter, which are all or nothing -- after all, on email I have the option to more than mute, such as to classify the message based on various parameters.
