I don't think that news needs to be defined as 'important' against an objective standard. Of course "Tiger Wood hurts finger" isn't objectively time sensitive.

I don't think that news needs to be defined as 'important' against an objective standard. Of course "Tiger Wood hurts finger" isn't objectively time sensitive. If it is important to you, you could read about it in a monthly with no consequences. It appears & is read in dailies regardless. It is news if it interests people. If it is news, speed is probably an issue. People like to be in the loop for (possibly) irrational reasons. You are trying to make the time sensitivity of a news item objective by attaching actionability to it. Most news is not actionable. People want it fast regardless. I don't think it is even controversial that "you heard it here first" is important to most news outlets.
