2. Selection:
Not all information is equal.  This doesn't mean that some of it should
be thrown away, though inevitably there is some waste in the information
world.  And this is not in support of censorship.  But there's a
difference between a piece on nuclear physics by a Nobel laureate and a
physics diorama entered into a science fair by an 8-year-old.  And
there's a difference between alpha release .03 and beta 1.2 of a
software package.  If we can't differentiate between these, our
intellectual future looks grim indeed.

Certain sources become known for their general reliability, their
timeliness, etc.  We have to make these judgments because the sheer
quantity of information is too large for us to spend our time with
lesser works when we haven't yet encountered the greats.

This kind of selection needs to be done with an understanding of a
discipline and understanding of the users of a body of knowledge.  The
process of selection overlaps with our concept of education, where
members of our society are directed to a particular body of knowledge
that we hold to be key to our understanding of the world.
