Storify is a great resource to assemble social media postings into a coherent story.

Andy Carvin of NPR has been in the forefront of working social media to tell the story of the Arab uprisings.

His latest example is a Storify posting that quickly debunked an assertion that Israeli arms were being used by the Libyan forces against the insurgency.

It is well worth a look for the story itself but also how Carvin was alerted to the story, how he fact-checked it and how he assembled it.

How to debunk a rumor.
