The 2013 SXSE question Resources and references on the topic of space exploration was kindly migrated to meta, and recognizing the value of a central source, 5 answers were posted with a really nice cross-section of resources listed. This is one of those rare exceptions to "list" questions where the benefits to the whole community were recognized and an exception made.
Had I not caught the recent question How would one go about learning rocket science? [on hold] with closing imminent (4 close votes after only 3 hours) it's possible the user would never have known about the helpful collection.
There's several options, including moving to meta then marking as duplicate, but the problem is (probably) that the first four close-voters had never seen the question in meta and all of it's helpful goodies.
I'm sure if one of them knew about it, something better and more helpful would have happened than a solitary You did something wrong and a complementary down vote, without even a link to help or take the tour, much less a "welcome to SE".
Question: Are there some ways to raise awareness of helpful collections of resources? At least the one "Resources and references..." that I've linked to above?
(there's also this one for example with 10 answers)
As an aside, there are indeed plenty of well received questions here and in other SE sites that ask for resources. Of course SE can be and is used to ask for resources. The issue is with the breadth of the question and unlimited number of possible answers with the general wording. At the minimum, when leaving the you've done something wrong and the complementary down vote, we should at least make an effort to explain correctly how to improve this or future questions.
