Digg and story duplication...

As I'm sure you all can see, I'm becoming a regular user of Digg. Not to find new stories but to share stories I read about and to post them to my blog. I know I could simply link and blog news articles to my blog using the standard 'BlogThis!' feature, but I feel with Digg, I can share with a larger audience. One of the features I like about Digg is that I can then also see who else is reading and sharing the same stories. This all said anytime you post a story, it first checks if anyone else has posted the same story and if not... it lets you post it and then it asks you to verify that it is not a duplicate. Now here is my 'issue' do you say it is 'original' since the particular story is not yet posted or do you say it is duplicate since a very similar story is already posted. Better yet, if you know a story was provided by the AP/BBC/Reuters/etc... but you read it on your local post or source, is it original or duplicate.... I guess this is one feature I'd like to see Digg incorporate... story 'grouping'. Basically while a story may be 'original' since the particular link has yet to be posted but if it is the basically the same as another story, group them. I see this having two affects... 1: users will be able to find others that have dugg similar stories (or the same under a different name) and 2: help users find other news/information sources based on those that are 'grouped' to story they just read. Now this all said, I don't think that Digg should combine Digg scores, I think the count at a particular source is valuable information, I just want to see other stories in my 'group'.
