Regarding the recent discussion on 'be welcoming', here's an example:
Where can one find safety regulations for storing, handling, and using rocket fuels - this question got put on hold for being too broad.
While I can see that point, I can also see that this user isn't expecting a complete and rigorous answer. He just needs a starting point, which fits neatly in a 3-paragraph SE answer. It's also an answer that can't be easily arrived at by Googling.
IMO this is what the 'be welcoming' discussion is about: closing questions by new users instead of helping them on their way. Or am I reading this situation incorrectly?
