This last one is dubious.  I have no way of saying, find me all
occurences of "Sprint" (as a proper noun, ie. name) in a document
or set of documents, skipping "sprint" the verb or noun.  Obiously,
"... winning the men's 100m sprint." does not pertain to
telecommunications or American corporate culture.

A lot of the things you mention are superficial.  They still don't
scratch the surface of *semantic* tagging of information.

We are creating and stocking quantities of information that will
be used well into the next century.  Machines will be used to
search these enormous quantites of data.  If it isn't tagged
meaningfully now (at its inception), it never will be.  And that
will be a real shame.

Whoopie.

To be honest there aren't that many.
