There are a few people who make very many submissions. Some people submit more than 2 stories per day, every day. And those are often duplicates-but-different source of other articles already on HN.

Better enforcement of the deeply interesting guideline would help but stories that are intensely interesting get many upvotes so it's unlikely to change.

If there was a submission quota, either time-based or karma-based, the "new" page would clear up rapidly, especially if obvious spam was not displayed as well (though that may be a result of my "show dead" setting).

Perhaps it would work to have users earn posting tokens by upvoting new stories. Need to find a balance of upvotes to token for a good flow. Would foster attention to the new articles and reduce the rate of new submissions.
