See the title. Can I ask when that action is meant to be taken?
See, I thought that comments on a question/answer are moved elsewhere when it is a handful of people discussing a topic at length that's starting to drift away from the subject of the thing originally replied to. It's becoming irrelevant and annoying to people not in the conversation, and thus should rightfully be moved to its own place.
Instead, what I am seeing is that comments are moved to chat when a certain quantity of comments is reached. When there's like a dozen comments, they have to go, regardless of whether they are on-topic, and whether the people involved were replying to each other or in fact all having different things to say.
That means potentially helpful comments are moved away, like clarifications or a debate on whether it's a relevant question. Those comments may then get posted again by new users who don't see that those points have already been raised.
Example:
- How many pillows would you need to survive a fall from a church tower?
- What should a god put on an island, so that its human settlers will more quickly achieve an industrialised society?
So, it's very probable that I simply don't get the purpose of this moderator decision, and that there are legit reasons for moving a dozen comments having nothing to do with each other. I hope to understand it.
