Getting started with the Workbench
I think you should lead visitors to your site through a recommended path: What should they do first and second? Can they pick some in preference to some others and still learn what they want to learn? How much of prerequisite knowledge should they have? Hold my hands and take me in, instead of expecting me to poke here and there.
A tutorial (mini-course on Big Data University) is being created which will provide a guided tour and help users get started with using various tools within the Workbench.
