Where do I ask questions about data explorer?
I am starting to use the Data Explorer. I would like comments and suggestions about a recent query I saved there (I will give the permalink in comments if some people want to, but I don't want to mix a usage question with its application). I noticed that there is no meta.data.stackexchange.com. I have not been able to find a chatroom dedicated to it.
What is the right place to ask for this?
Here at meta.stackoverflow.com? (But most questions I have seen here about data explorer report bugs or feature-requests)
In a chat room of meta.SE?
In the meta of the SE site with which I first tested this query?
In a chat room of the same SE site?
