Twitter employees mapped: how are they connected? - The Guardian (blog)

How do groups of people who work for one company link up on Twitter? Designer Santiago Ortiz made this visualisation looking - appropriately enough - at employees of Twitter. Using only the public profile of users via the Twitter API and the @Twitterteam list, his visualisation shows in incredible detail the way that people interconnect, just within one organisation. Hover over a node to see which user it is and click 'play' to see those networks change over time. This is also the first public face of his new network visualisation tool. Which other organisations could it show?
