I'm sorry for the confusing title, but let's consider the following two questions, which are recently modified on the main site:
(1) Is there any way to get real-time compilation for LaTeX?
- Asked in 2010

- The accepted answer is posted in 2010 and has received 34 upvotes so far
- Asked in 2008
- 75 upvotes
- 41417 views (until 06:26 Jan 3, 2019 UTC Time)
- The accepted answer is posted in 2009 and has received 34 upvotes so far
Question (2) is marked as a duplicate of Question (1).
But why?
We can see that Question (2) was asked and got the accepted answer before Question (1) did! (2) also has received more views and more upvotes, i.e., (2) is more popular.
If the two questions are a duplicate of each other, I think that Question (1), instead of Question (2), should really be marked as a duplicate.
However, I think they are not a duplicate of each other at all. The accepted answers are not the same, or at least similar, at all, from my point of view.
