I have came across to this situation a couple of times.
One guy (or my self) ask something like:
How can I delete the whole filesystem in LISP
Is there a way I can shoot myself in the foot using HTML
And people answer back:
What's wrong with you? You should not do that, you should do this or the other etc. and the (we have to admit it) stupid question gets down voted while the "comment" placed where the answer should go, gets upvoted.
The comments are very useful indeed (sometimes I have my head in another planet and ask stupid questions), but they should go in the comment section, not in the answer section.
If the user in turn don't know the answer, please don't post an answer, post a comment.
When the question is in the form "Is it ok to shook my self in the foot or in the arm?" Well, that's a different story, here you are asking for the opinion, and then an acceptable answer is "Are you stup..." etc. etc. But I don't think it is something we should do when the user is asking something very specific.
Now, what is your opinion?
