Valdis Krebs has another news-related network analysis in Power in Economic Networks. This time, covering the European natural gas network, which is dominated by Russia.
The golden rule of networks is the same as the golden rule of Real Estate -- location, location, location. Find a good location, and you may have some power over the network. End up in a bad location in the network and you may get very cold while you helplessly watch others maneuver.
I know Valdis doesn't always have a lot of time to do these, but it's always nice to see them pop up on his blog or other locations. Thanks, Valdis!
