I noticed Why do we need private variables? got closed as a duplicate of Do ALL your variables need to be declared private?, but I thought the first question and its answers were much better than the second one.
This isn't the first time I've noticed a question getting closed as a duplicate to what I view as a worse version of the question. This is probably because new questions get more attention, so are more likely to attract close-as-duplicate votes than older questions.
Is this something I should be concerned about?
Personally I'd rather have the best version of the question left open, and the worse versions closed as duplicates, but I'm not sure if that's something I should flag moderators over.
update
Question has been reopened.
