McAfee would tel you that email is a channel (i.e 1 to 1, not searchable etc ..) while E20 is based on platforms (many people accessing, searchable as data is persisted and indexed with tags etc …)/

Funnily enough, I'm not sure that CEO are the most relunctant in adoption 2.0 approaches. From many of the studies on the topic, we found out that Managers were. Bringing E20 bring transparency, fluidity, disintermediation, all this elements that make middle managers pretty uncomfortable with the whole thing.

The advanatge in deploying on small scale s that you can reach small milestones and foster small vitories. This helps in giving momentum to the project.

Agree with you : observability is key. But compatibility and complexity also are.

My stance is always Observability is key. I think that the internet has made a lot of headway in the domain of analytics and copywriting for effect. We are in a new age of writers, where people are constantly exchanging thoughts on how to better present information so that readers can use it. Some of those lessons should be applicable on a private networking environment. Observability is also key when dealing with the most conservative people in an organisation, usually the ones paying the bills.

Generally, I like the idea of deploying e2.0 systems on a small scale to see how effective such a system really is. I have my doubts. Just like Google Buzz isn't really an innovation over Gmail, because email is already a social network, I think there are plenty of social networks in place in organizations, they are just not labeled as such.
