2.0 Adoption Council (What is)
Susan Scrupski of ITSInsider hatched this idea after the June 2009 Enterprise 2.0 Conference in Boston, MA earlier this year. About the council, she says:
We are a collection of managers in large enterprises that are charting the course for 2.0 adoption. Although we may use different platforms and tools, we all share a common enthusiasm for bringing a new way of working to our representative companies. We call ourselves “internal evangelists” and some say we have one of the most difficult, yet exciting jobs in the global marketplace.
To qualify for membership, you must work for a company with more than 10,000 employees and your full time job must be about bringing 2.0 technologies and behaviors to the enterprise.
The council is by invitation-only, but you can apply to become a member of the Council by sending them an inquiry on LinkedIn. They’ll get back to you in 48 hours.

Thanks, Gia. There’s also a limit of 2 reps per company, I’m told.
