I like to add questions and answers to help topics based on what I see people mentioning that they don't quite understand in questions, answers, and comments. Or if I just think it would be helpful to people in general.
Here are some of the Q&As I've started with this idea in mind, to give you an idea of the type of Q&A I'm talking about:
While doing this, I've received a couple comments on some of the different Q&As, that the questions were easily googled and the correct answers came up right away, so that I shouldn't be putting them on our site.
I don't see any reason why we can't have our own versions on our site. That way if one of the other sites gets turned off or something, our copy would be available. On the other hand, I can see for some of the topics, that there are already so many articles on it, that I would just be adding another copy among dozens of others.
So if the topic is already covered by other sites, should I be spending my time covering the topics here? Or should I be pointing people to the topics on other sites if they have questions?
