Thanks to Joachim Niemeier, I found these five recommendations for IT managers considering deploying web 2.0 technologies in the enterprise (in the sidebar of the article - provided by Andrew McAfee):

1. Provide a forum or platform where employees can collaborate and communicate. McAfee noted that knowledge management systems enable this sort of activity already. But unlike the traditional knowledge management system, Enterprise 2.0 collaboration is employee-driven. Managers don’t dictate the terms of that collaboration.
2. Set up an enterprise wiki and demonstrate it to influential people within the company to help drive interest in using it.
3. Set up internal blogs for all employees and incorporate them into internal directories so users can see who has a blog.
4. Try setting up an enterprise social bookmarking system so users can see what sort of content their colleagues are tagging on the Internet.
5. Be in on it from the beginning by making sure the right infrastructure is in place.
