I'm sorry, did I miss the part where they said they would only monitor Twitter? Or am I remembering correctly where they used the broad, sweeping term "social networks", which would include Facebook, and I'm sure BBM chat.

Do you live in a fantastical world where governments pass very strictly limited, narrowly defined laws that precisely target one specific problem? Because here on earth the rule is overbroad laws made by ignorant legislators.

No, but the OP specifically mentioned twitter.

More generally I think we should wait until the government comes out with a formal proposal rather than getting all hung up on a soundbite.
