Smart move by Twitter:

Mark Little, the founder of News Corp owned social news agency Storyful, has been hired as a senior executive across Twitter’s international operation.

Few people have been as successful in recognising the potential of combining the output of new and social media with the values of traditional media as Mark. Storyful led the way on systemic verification and use of material from social networks in mainstream reporting.

As Twitter is very clearly interested in exploring that intersection further, Mark seems like a really good hire for them.
