It has the capability to directly download membership data from many popular social networks. This data is processed and the program can calculate network characteristics parameters. It also draws a network connectivity diagram. A brief overview of the use of the program is shown in the video below by the the program creator:
2009 - November - NodeXL - Demo - Mapping Twitter Social Networks "Digg" from Marc Smith on Vimeo.

Social network visualization diagrams are very interesting. They provide a snapshot of connectivity that will not be obvious by looking at the raw data.
Right now these plots are restricted to only one social network at a time. Also, the social networks put limits on how much and what kind of data can accessed from their website.
NodeXl is gaining popularity among academics. A number of instructors have been using to help teaching social network analysis. A book entitled " Analyzing Social Media Networks with Microsoft NodeXL Book" will be published in few months time. The outline of the book can be obtained here http://bit.ly/cCFEXD
