I am new here (at least as an answerer, though I have been checking the "hot" questions and answers for several months now).
My question is:
Any question will have a "first" answer at some point of time. I have noticed that most of the answers have the critical (giveaway/spoiler) parts "hidden" until we hover the mouse-pointer over them. My understanding was this is to help other answerers independently "try" to answer on their own.
Now I realise that even an innocent/independent "duplicate" answer may be frowned upon. So, if a (reasonably new) question has an answer (or more) already with the "hidden" parts, do I "uncover" them and see them first to ensure I am not repeating one of them? If yes, why even "hide" them in the first place? What am I missing here?
