First time I have come across a question with an incorrect answer.
A little disappointing for a novice like myself.
I find that even for questions that are well and correctly written, the discussion holds additional information. So it's almost always worthwhile to read the discussion, even if the question is poorly written. I treat the questions as more of an introduction to a topic of the day.
I also try to keep in mind that the questions are written by the community, and so will reflect the varying levels of knowledge and skill out there.
Having said that, question authors should at least run the code they write and make sure that their answer is correct in that respect.
