The simple idea that people’s actions model meaning better than a
directory (even a flexible directory) is a critical step forward in
thinking about the Web. The innovation we’re seeing with
folksonomies, recommendation systems, social networking
sites…all have their roots in the idea that modeling what people
actually do on the Web is the best way to provide answers for them.
And, perhaps more importantly, it is an admission that we simply
can’t predict the future…we can’t design a perfect
information architecture, and to attempt to implies that the world
we’re modeling doesn’t change.
