The Data Explorer is great. But there seems to be no natural place to request modifications to a given query or to request a desired new query.

To give one example, on the Most closed tags query, one might want to request a query that also computes the closure rate as a percentage of all questions asked in that tag.

If we had at least comment functionality, we could ask the script-writer for a simple change. And we could also propose improvements or link to improved versions of the query.

But even more useful would be a natural forum where one could make wish-list requests for queries. Why doesn't the Data Explorer follow something closer to the standard StackExchange question/answer/voting/comment format?
