From the links bellow, I find that there are the benefits of Enterprise 2.0 :

  • Possibility to show and share information
  • Possibility to explain with ideas for employees out of different levels or news for clients (as examples)

Among the risks:

  • If somebody for fun on intentionally launches a damaging statement or “rubbish” idea, other people may spend time in unproductive way, getting distracted from main duties and getting distressed.

Take a look at links below for some interesting examples:
