(Irony here being that my question might, itself, not be a particularly good question)
One of the joys of being a senior member of an engineering teem is that you often get asked questions - either of things you have direct knowledge of or things that you're simply better at Google-ing. The problem is, it seems like a lot of questions lack the obviousness that the asker assumes is in their question. So, how do you teach people to ask good questions?
Bonus, here, is that once you've taught them how to ask good questions, you've probably also taught them how to more effectively use Google (et. al.) in the process.
