The [Data Explorer](http://data.stackexchange.com/) 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](http://data.stackexchange.com/mathoverflow/query/78395/most-closed-tags-in-stackoverflow-top-20) 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?
