We all have our different obsessions, er, interests. :-)

I agree with your comment about styles.  Given my work and browsing styles,
I would rather have an agent that presents a small amount of filtered
information to me; if I have to browse for (or even search for) my target
among lots of tangentially related materials, I'm much more likely to be
drawn off on a tangent.  Naturally, I would *also* want access to the
better search engines.

There's a seductive and dangerous notion that filtering will *prevent* one
from seeing the critical bit of information one seeks, while search engines
and direct-manipulation interfaces will let you sift through *all* the
information to find the bits you want.  I'm beginning to realize that
flooding my attention with all the information I can scan, counting on
my focusing mechanisms to notice and sieze items of interest, just
doesn't work.  Perhaps it works for others.

I'd be happy to see workable and usable ontologies.  I tend to be skeptical
about this goal, as you are skeptical about the AI technology agents may
require.  I'll be surprised if we can come up with a set of really good
standard ontologies -- but I *love* that kind of surprise!
