It's a tough one.
Campaign research and world-building are pretty integral to RPGs. They're definitely something we SHOULD be able to cover in some way. That said, I think that we should definitely be tying the RPG we're targeting into the question in some way.
So far as the CW vs. not CW issue is concerned, if the question is looking for a list of resources (Where do I go to... What do I read to...), I would favor the CW format. As someone approaching an already asked question I just don't find a group of massive lists with comments saying "+1 for this" and "+1 for that" to be terribly useful. It's difficult to parse out which aspects of each answer were actually helpful to people. As a voter I also feel constrained, because I feel like I should only be voting for the one best answer instead of up/down voting whenever I see something interesting/not interesting.
On the other hand, if the question is "How do I build a city for ...", or "how do I capture the feel of..." I think that non-CW is appropriate. That sort of question is naturally going to lead to more original content, and will somewhat sidestep the massive list of links problem.
Of course, this has just been my outlook on the matter. The community has been tending away from CW for list questions.
