A user answered the question twice with 2 different suggestions. I originally thought this was in bad form as an attempt to get extra votes for what should have been one answer containing multiple solutions. To which I added a comment:
I would just merge these responses as one. You don't really need to have two answers for this.
And the user responded with an acceptable motivation:
It was two different approaches, so I figured it's two different answers. Each can get up/down voted independently.
In that same question another user has one answer with 2 suggestions. I'm sure we have all seen, or even ourselves, answered questions with single answers that contain multiple solutions.
I think that this is not the approach we should be taking. I see multiple answers from the same person as one response. I would only entertain multiple answers if each one is of great length and vastly different. Is this something we should be discouraging.
