Fabernovel (a consulting cie) made a interesting study and a Facebook analysis.

If you want to understand the "social media" revolution, you will see a phenomenon in action.

A few points as a conclusion

The phenomenon is only starting and will be strongly influenced by the new applications available

Privacy is an issue

Brands and companies should learn how FaceBook enables a new communication with their consumers

Offers new collaboration and knowledge sharing opportunities:

- Quickly spread successful ideas and recruit for projects or causes
- Let users manage what they do not want to share instead of asking them to make an effort to share
