Some news sites double up on stories. They sways have the same headings. Allow duplicates to be combined.
Would be the killer feature... How I would implement it:
1. try get tags
2. Compare tags
3. Choose about how many words and videos there are in the article
4. Only show the best related to the information at point 3
5. Enjoy a cleaner feed

This also applies to many sites that repost another site's article. This creates a lot of duplicate articles in a feed.
Gave 3 votes since this would likely be a "monstre feature" because of its usefulness and technical complexity.
