It's not a million miles from my preferred solution to a similar problem.
I tend to exist in RSS, so wouldn't remove much by syncing with the rest of the web.
But what would really help is a way to check for duplication between my subscriptions, and the people I follow who share the same article.
I often see 3 or 4 of the same article appearing in my feeds, which is really annoying, as well as wasting time...
I get my content from a lot of RSS feeds, plus HN, plus Rediit, plus all the other miscellaneous places one finds links.
It'd be neat if there was a way to detect when a piece of content was just a reblog of some picture or article or link that's doing the rounds: maybe if the content is only a link plus less than a hundred words?
Right, and then bring together all those related posts, so I have the links to both the reddit comments and the HN comments in the same context as the original article link.
