More and more developers and architects realise that learning every detail of a new API just isn't the way to deliver the best business value. It's such a tough balancing act: focus on the solving the business problem and focus on building working software with your frameworks.

One way of taking a big leap in the right direction is to learn and apply domain driven design. It is definitely not abstract and fluffy; it deals a lot with the code also. DDD leads us to focus on understanding and to communicate that understanding very well; in language, in design and in code. You will shift your focus away from designing for a technology, and you will learn to design for the business domain; to the core of the problems and solutions. Those are the most interesting parts and what your users and customers really care about.
