When writing a story think about:
Impact
How many people are affected by the story?
Will it have an affect on their lives or pocketbooks?
Timeliness/ Immediacy
News is supposed to be new.
Get the story out there and quick (but make sure your info is correct)
Proximity
The closer to home, the more newsworthy the story.
Prominence
Names make news.
Does the story involve a well-known celebrity?
