Cadmus Groups Duplicate Tweets, Actually Works
Louis Grey posted about Cadmus earlier today, and the idea of grouping duplicate tweets to remove noise is a great one.
Better yet, it actually seems to work. For Tweets anyway. Cadmus also supports FriendFeed and RSS, but I haven't had luck with RSS yet. I had some odd results importing my 150-ish subscription Google Reader OPML. It pulled in thousands of old items in no discernible order. But it did group 30% of them...
Here's Cadmus in action, grabbing 8 posts regarding Google's acquisition of Gizmo5 and rolling them into a single nested tweet. By clicking "Related Posts", you expand the grouped duplicates. Now THAT is cool.
