[tdwg] Interesting example of tree navigation

This begs the question:  has this style of user-interface failed to catch on
more widely because of:

1) Technological limitations;
2) Insufficient creativity and inspiration; or
3) Insufficient usability?

I'm tempted to eliminate #3 on the grounds that I don't think this style of
UI has been widespread enough to have been subjected to, and then failed,
some sort of usability meta-experiment.

This is not to say that it won't ultimately fail such a meta-experiment --
just that it hasn't really had a chance to fail it yet.
