Alot of times I'll see questions, often linked to by other duplicate questions (that are usually not actually duplicates, but that's a different issue) that are closed or locked after being marked as duplicate or for other reasons. There will be a few comments relating to the locking, but no answers.
As these questions are officially the same as the duplicates, and because the duplicates have answers and aren't locked, why do the orphan questions even get linked to? They seem to be completely useless.
Looking at the specific question that caused me to ask this, it was actually "merged" with the duplicate. Even so, it still doesn't serve any purpose that I can tell.
