Contrary to the author's opinion, BS isn't hard to maintain and the code isn't messy. I've developed more than 30 projects using BS as the framework. It has enabled me to prototype, as well as build for production, faster, cleaner and better. Might there still be something better out there? Sure, but there are definitely cons to continuously changing your tool set and diverting yourself from actual building. Imagine if a carpenter bought a new power saw every time a company introduced a slightly improved model. The economics of that should be clear.
