I find it annoying to see the same stories duplicated in my Google Reader, especially now that I subscribe to many popular/recommended feeds (RSSmeme, del.icio.us, TwitBuzz, Twitt(url)y, ReadBurner, Hacker News) along with my regular feeds.
I just updated it to version 0.2 today with a couple of changes:
- moved Remove Dupes button next to the Refresh button
- dupes: mark as read, but no longer hides them (fix keyboard j,k bug)
- finds more dupes by splitting symbols (-, |) this is really helpful if you subscribe to Twitt(url)y
- more helpful firebug console output (ie. # dupes removed)
You can install this script from userscripts.org.
My other greasemonkey script is for adding ratings to the RedBox website.
Let me know what you think!
