Granted you can get a performance boost from denormalizing, and even maintain integrity, I still find the denormalization I want today won't be the denormalization I want tomorrow. Moving from denormalization to denormalization can be hard, and you end up with a sui generis application, versus a normalized database where so much has been written about how to deal with problems up to a reasonably large scale, although the document store style does seem to be reasonably popular so maybe I'm missing something.
