I just realized that there are several questions on Stack Overflow with very similar titles, such as Generics in Java and Java Generics (capitalization may differ). Today, Can I add to a generic collection of type A values of type B ,which extends A, without any special syntax? was asked; in my opinion it covered exactly the same ground as one of the previous questions. (the OP has since modified the title.)
If a user asks a question with exactly the same title as a previous one, then this cannot be a good thing:
- The questions are the same, in which case it would be a duplicate.
- They are not the same, in which case they should not have the same title.
The second point might be relaxed to allowing questions to have identical titles if their main tags (tags with highest frequency) are different (e.g. one is about Java, while the other is about Python).
Could something like this be implemented? Do other people here think this is useful? Do you have arguments against it?
