Trends of social media

What are the major trends in social media? A report by McKinsey Quarterly presented 10 trends in their edition of August 2010 as a result of a McKinsey survey of global leaders. They are listed bellow with a short description that I've added myself:

1. Distributed cocreation moves into the mainstream
   Companies create value through web communities, examples: customer support, marketing and product development.
2. Making the network the organization
   Social media help map information and information flow. This can be used to identify talent (even external).
3. Collaboration at scale
   Social media can help employees collaborate better and reducing the issue of geographical distance.
4. The growing ‘Internet of Things’
   Things are embedded with sensors and create data on the use of the object.
5. Experimentation and big data
   Social media makes it easier to conduct experiments on a big scale (social networks can be mined for data).
6. Wiring for a sustainable world
   Companies are using social media and IT to reduce their environmental footprint while profiting economically from it (nice).
7. Imagining anything as a service
   Customers are getting accustomed to paying for what they use, products are becoming services. Examples: could-computing, ZipCar etc.
8. The age of the multisided business model
   Models where all involved parties benefit. One example is companies providing free services while gathering and selling data on how these are used, like patientslikeme.com and MasterCard
9. Innovating from the bottom of the pyramid
   Disruptive business models are arising from extreme market conditions (like in India or Africa) and new technology, example: Safaricom offering banking services through its mobile-phone services. These business models are immigrating to developed countries.
10. Producing public good on the grid
    Public policies that incorporate new technology can help on economic and social strains of population density.  

How are these impacting leadership? I will explore the trends of social media and choose the ones that have the greatest impact on leadership. Then I will test these by interviewing Norwegian leaders that has excelled with social media. Do you know anybody?
