I agree to Jon’s answerJon’s answer here in almost every sentence. But even if the question at hand can look trivial to experts, imagine what kind of qualitative answer an expert could give. The one asking could have been searching for a User Experience term, and find various of good and bad answers and really need to verify what this term means, not only in an academic view, but also from and industrial professional view.
So on one hand I think we should be the last line of reference even for those learning User Experience and who aren’t skilled enough yet. On the other hand, I totally agree to Jon’s answer, since we should only allow high quality answers.
We already have a high answering percentage, and adding a few term-explaining questions, would expand the UX community usefulness for those on their way of becoming experts.
