Networks are a data structure commonly found in any social media service that allows populations to author collections of connections.  The Social Media Research Foundation’s NodeXL project makes analysis of social media networks accessible to most users of the Excel spreadsheet application.  With NodeXL, network charts become as easy to create as pie charts.  Recent research created by applying the tool to a range of social media networks has already revealed the variations in network structures present in online social spaces.  A review of the tool and images of Twitter, flickr, YouTube, Facebook and email networks will be presented.
