Yeah right…Get real!
With such a “technarian” approach many Enterprise 2.0 initiatives will turn out to be nothing more than a sheep in wolf’s clothing. They will lack sharp enough teeth to make the change go deep and really stick into the body and mind of the organizations. The initiatives that will succeed - despite the technarian approach - are the ones which are happening in organizations where the existing culture is based on principles such as openness, transparency, trust and participation. These organizations have probably already embraced social technologies and practices.
Here is my two cents.
If change is not sparked and embraced by a critical mass of grassroots and informal leaders in the workforce, then change will not come. If management does not allow the sparks to turn into fire and bring some fuel to keep it burning, then change will not spread and stick. Social tools and platforms will just end up in the pile of old collaborative technologies which never "worked" because they didn't deliver to their promises (because they didn't make people change the way intended to).
Update: as Martin King wrote in a comment to this post it "can be even worse - without behavioural changes the technology is used to exert and reinforce existing practice e.g. command and control."
