I like to give an analogy of a car (cars = themes, bear with me). When building a new car, everything isn’t reinvented. Your not going to find innovation in tires or in a steering wheel from the new Dodge Grand Caravan. Instead, you’d probably find innovation through the features it sports. What results, is a lot of cars using the same parts. So can WordPress themes. It’s all about being more efficient in your craft. Factor out all the essential theme parts and use them as the bases for the framework. In doing this, you’ll dramatically speed up the time it takes to build recurring themes from scratch.
