Corporations that replaced their Intranets with Web 2.0

Firms that replaced intranets with blogs, wikis, facebook or a combo:

• RAND Corporation  http://www.rand.org/ blogs
• Jenkins Law Library http://www.jenkinslaw.org/ blogs and wikis
• Serena Software  http://blogs.zdnet.com/service-oriented/?p=1011 facebook

I’m guessing here:

• IBM ( they use a ton of internal blogs but not sure if they still have an intranet as well.)
