Technical challenges for next generation web info systems

[James Mason]

I'd like to identify as many hard technical/
scientific problems and challenges we face 
in building new generations of web information technologies in terms of
navigation, visualization, 
document similarity, and other issues.

Can you suggest avenues to collect such
problems/challenges or help build a list
itself?
