I'd like to suggest a feature that would help to alleviate articles appearing multiple times on the same page.
Feature: Add a query rule for "asset must be unique". This would make sure that an asset is shown only once on a given page.
Possible Implementation: Global array at page initialization holds array of unique asset ids. As assets are added to the page block by block, the asset ids are added to the array. If the query rule is checked, then when the query for that block is made, the global array of used ids is passed along as a "AND id NOT IN (list of used ids)".
1) What problem does this solve?

2) Why do we need it?
