I attended the Mobile Web Africa conference in Johannesburg, South
Africa. The conference was a rich source of insight into the ways
mobile technologies are changing the lives of millions of Africans.
The conference used Twitter and the hash tag #mwa09 to gather all the
tweets about the presentations.
I used NodeXL (http://www.codeplex.com/nodexl) to collect these tweets
and map the links between each user account.
In this image the nodes are located based on their connections to
other nodes, revealing concentrations of ties between user accounts.

The book, Analyzing social media networks with NodeXL: Insights from a connected world, is available from Morgan Kaufmann and from Amazon.
