Code frameworks and ghettos, where creativity gets a lock-in

An acute issue in programmer productivity lies in framework learning curve. More often than not, no framework can be more productive than having to learn a new one. A code framework can be a force for good when it solves infrastructural issues and allow developers to concentrate on the specific job at hand. When the job is about addressing a user need, then it is well worth investigating the benefits of any framework before diving in head first. But when the job itself is about infrastructure, then the story could get more complicated.
