Drew at Holy Whapping has interesting thoughts:

The Exhortation plays an important role in this movement, then, by codifying Ratzinger’s ideas on liturgy into the written magisterium of the Church. He gave the reform of the reform much of its steam by expressing these ideas in popular books; it can only continue to pick up steam now that these ideas are more fully incorporated into the magisterium. The momentum of liturgy seems, from my vantage, to be clearly swinging in favor of a this reforming of the reform: by this exhortation, will it not continue to pick up speed, and continue to be desired by the people and priests themselves? Certainly, creating an environment in which the Church wants the "reform of the reform," though this takes longer than reform by fiat, is more effective in the long run. It may be less satisfying than a glorious smack-over-the-head delivered to those with whom one disagrees, but glorious smacks-over-the-head are not effective in the long term. How many people, pining for a liturgical smack down akin to Pius X’s smack-down against "Modernism," are willing to concede that Modernism dissapeared consequent to being "smacked down?"

After Mass today, I met one of the seminarians for my diocese–a reverent guy my age, also in love with the Church. These future leaders of the Church have had their hearts moved and formed by the exhortations of Cardinal Ratzinger and Benedict XVI, and it is precisely to loving and willing hearts that exhortations are recieved and by them are enacted. This exhortation, then, is a seed planted in the heart of those who want to reform the liturgy and the Church, and it is precisely the desire to reform the Church, it seems to me, which is the way to effect a reform of the Church that is sincere and lasting. Reform of the Church, then, begins in the reform of the heart–and in exhorting the willing heart. It is easy to call such Christian exhortation "ineffective" because the effects take time to come to fruition: but is that ineffective governance, or is it good psychology? Reform by fiat, which is not also reform of the hearts of Christians, waits only until the cat is away to quickly decay.

And as for me in my house…I have to distill the 31,000 words of this Exhortation into between 1500-1700 words, and I have to do it Wednesday morning. So, if I’m scarce (which I had better be!)  that’s why.
