Be careful to not confuse the metaphor with what it’s supposed to represent. With that in mind:
What do you consider an “idea”? Are you talking about things that practical, epistemic (true/false) or moral (good/bad) in nature?
What do you consider a “helpful” or “beneficial” idea? And helpful/beneficial for whom?
What’s the target audience those ideas? Everyone, or 1+ specific groups?
Who’s “we” in your “we can”? In other words, who’s willing to help you out?
From circling those questions you’ll probably find unclear spots on your goal. And once you find those spots, and get rid of them, you’ll be able to pragmatically list potential solutions, their pros and cons.
Note that trying to do too much will often yield practically no results. Even when dealing with abstract things, there’s a limit on the amount of work that you can do, and you can’t spread it too thin. Virality can help you out a bit with this though, as it allows you to relay work in a headless way.
