I've been on this site for a bit now, and I think I'm getting the hang of things, but one thing I don't really get is all this stuff with the Community Wiki questions and answers. I think I understand when a question/answer is supposed to become CW from posts like this one, but I don't really see the reason behind it. To get specific, here are some pointed questions:
Why are questions made CW: How does a question becoming CW benefit SE? As an asker, why would I want to make my question CW, given the choice to do so?
Why are answers made CW: How does an answer becoming CW benefit SE? As an asker, why would I want to make my question CW, given the choice to do so?
Please let me know if this question is still too vague, I tried :/. Any comments, links, or answers are appreciated.
