Just came across your blog. I’ve done a fair amount of searching for social network analysis software, and the most capable app I’ve come across is called InFlow. For more info on it, see http://www.orgnet.com.
It is targeted at consultant use in large enterprise projects, and is priced accordingly.
The others I’ve found are unsupported academic applications or applications developed by seemingly defunct organizations.
If you find other applications I’d like to hear about them.
It looks like they copied Morvile’s design: http://www.semanticstudios.com, otherwise a good site.
