My theory on this is that a majority of corporations will continue to pay lip service to transparency and the case studies cited in the article show perfectly the prevailing mindset. Of course, there will be pioneers but they will remain a minority for some time to come. Command and control are much harder to let go than many think.
As for the adoption of the new, just read in this same publication the statistics of how long it took for agencies to come around to the realization that interactive is where it's at. So, who do you expect driving the message home to the corporate suits that transparency is the new game in town, their lawyers? Hardly!
On the other hand, that's not all bad. Who would want to see all these YouTube masterpieces of corporate transparency anyway?
