"When writing, your first job is this: First, make me care."

It really depends on who the audience is...

[bravura]

Understanding your audience is your first job as a writer or communicator.

Speaking to them and making them care is job two.

[wtetzner]

Ideally you wouldn't need to make them care. Just give them enough information up front for them to determine if they care.
