Big Medium 2.0 Content Management Software
This site (and all the sites I create these days) was built with Big Medium.
Big Medium is the brainchild of a Parisian genius named Josh Clark.
I have been using this software for 5 years now and it is the best value around for a feature rich content management system.
The new version, 2.0, is incredibly user friendly. Once configured it requires almost no technical wizardry to maintain.
