I’ve been working with financial news for years now and there is a really common problem in financial news, deduplication. The issue is when several news outlets will cover the same story or even redistribute another sources story, creating duplicates that readers find annoying. As the web becomes more mashable, I saw the first sign of this same problem on FriendFeed today. One of the people I follow had both Twitter and Tumblr feeding into his FriendFeed. But, he also had Twitter feeding Tumblr. In flowed the dups!
He removed the Twitter to Tumblr feed to stop this, but it was a glimpse of a feature that FriendFeed is going to need to consider. In this instance, deduplication would be pretty easy since the content is exactly the same.
