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...
