The WR dictionary has this definition and example:
- a piece of advice, esp. on how to succeed in a certain area:gave the rookie some pointers on good batting.
Another example - "Hi, I'm Julia Child and today I'm going to give you a few pointers on how to cook a really good
boeuf bourgingnon."
Is there any special reason you think the word might be used by a specific group only? I can't think why it couldn't be used by anyone.
