How powerful are Sara Lee's Board of Directors? Might seem like a straightforward question, but with Josh On and the Futurefarmers' 'They Rule,' the often-invisible and surprisingly interconnected networks of blue chip board membership are made visible. One will be surprised by how few serve on so many Boards. The Flash-based interface of 'They Rule' relies on data last updated in 2001, but a 2003 version is said to be in the works. As well as creating your own map of who rules across which industries, you can browse and alter maps created by others, with titles like 'The Telecom Tango' and 'From Big Oil with Love.' See the 'Snack Cake Uber Alles' map for the answer to the question above. - Ryan Griffis
