I was browsing new questions when I saw this question already marked as a duplicate, since I happened to knew a possible answer I went to the linked question and considered I could provide new content so I answered it.
After that I noticed that, in fact, the old question answers didn't really answer the new one which was actually more defined while the old question couldn't really be answered except partially. By answering the old question I effectively made the new question a duplicate (which in my opinion wasn't before since it asked something different that wasn't answered in the old question).
Now, I know the duplicate doesn't need to be the newer question and I actually like to favour new question, specially if they are better defined, so I voted to re-open it. Was it OK to do that? What should we do?
Sorry for the long story, hope I made myself clear.
