We've had a couple of recent discussions about what constitutes a good answer:
- Is posting tables of information from commercial strategy guides a legal issue?
- Should we care if an answer is from Googled information, as long as it is right?
Both, I think, come from a problem where the information to answer the question is freely (or at least, easily) available elsewhere. Many of these types of questions are "fact recitation" questions, where it's hard not to copy from an external source, even if you know most or all of the answer, because your answer would not be substantively different from what's already out there.
This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information.
The idea being that Stack Exchange is for the stuff that isn't easily found elsewhere: that we don't do the Internet a solid by copying other people's work.
Something along these lines has been discussed here in the past, with a flowchart provided:
Does having this close reason make sense on Gaming? Would it help solve these problems at all?
