I think the doubles are a great part of the monthly challenge. It needs them to maintain the variety.

The reports on visual may not get the feedback but I'm sure their not ignored.
I ,myself, enjoy reading them and am guilty of not acknowledging them via a comment.
The monthly challenge also gives a plan for viewing where the decision of what to view has been made for me. Whether I've viewed the object before or not doesnt matter to me, re viewing objects increases the details.
