We are all likely very exhausted from all that blogging the last few weeks. I know I am.

So, this post will be another video about social networking. It might explain such things as:

- why are people within the city collectively grumpy, happy, or care-free?

- what does it mean to have 10,000 twitter followers?

- why is it true that birds of the same feather…flock together?

Video: the hidden influence of social networks.

Q&A with Nicholas Christakis.

Social networks are not and ends to some means, but a continuation on our desire to communicate with each other. The value in IT is of course in building applications that harness the virtues of a social network architecture. In advertising, understanding social networks has great value, too.

Note that these ideas based on Robert Putnam’s work on Social Capital.
