Hi,

Once again, my name is Branko Collin, not David Rothman. :-)

I wrote other articles about this topic, for instance Qualities of Paper (http://www.teleread.org/blog/?p=3752) at Teleread, and the far too fuzzy E-mail Usability (http://www.tekstadventure.nl/branko/...mail-usability) at my personal blog, in which the argument I am trying to make is that people use the metadata that the interface of their e-mail client provides them with to organize their documents. Sure, better interfaces may be imaginable, but as long as no-one introduces them, they will never catch on; and in the end, it may turn out that the filesystem is the best shoebox after all.
