Give information to people who can do something with it
Information is only of value if you give it to people with the ability to do something with it. The fact that I know something has zero value if I'm not the person who can make something better because of it.I am more scared of the bureaucrat that holds information in a desk drawer or a safe than the one who leaks, because ultimately we're better off if we share.
General Stanley McChrystal outlines why the military shares intelligence more than it used to, even when it risks that information being leaked.
There is, I hope, value in working in the open, in sharing what you're learning, what you find interesting. Someone else may be able make use of what you've learned even if you don't.
