It'd be alot cooler if it could be used for an application that many people use. LiveJournal is too much of a niche to get a good view of a social network.

Not new... been our for a long time.

MPL - i actually disagree with you. Any visualization of networked data is interesting and it all provides an entirely different slant on an individual's life. LiveJournal may not reflect your network (or mine), but the network that it does reflect is quite valuable and interesting. This kind of work is one step in the right direction.

funny... almost at the same time I found this browser. One week later I was posting the portuguese network with more than 5 friends.
(check this link: http://www.livejournal.com/users/ulis/137986.html )

There are almost 500 users registered in Portugal.
340 were active (last update with less than 2 months)
68 were "double-clicked / expanded" All with nore than 5 friends
The result was a strong connection to Brazil, photo journals and generic english users.
