Mixx, a McLean, VA-based social news start-up that competes with the likes of Digg and Reddit will roll out a new feature that allows news-submitters to add more context to their submissions. I have started using Mixx recently and have been impressed by the content being posted to their site.

Anyway this new feature of which I got a sneak peak, is actually a smart move by the company. It allows MIXX users to add links to additional stories, press releases, photos and video clips and give more context/depth to the original news stories. It will be rolled out later this week.

In many ways these contextual links make the story suggestions more valuable, as it can help form clusters of search-engine friendly topics that have relevance long after a story has lost its news value. Screenshots below the fold.
