david brings up an excellent point, one that i have been asking 
(mainly to mike dean) since the program start.  however, i think his 
problem statement is not quite right, and his potential solution is 
not what i would recommend.  i wouldn't state the problem as, "why 
should i use DAML + OIL," but rather, "what does DAML + OIL provide 
to me over XML + XML schema + RDF + RDF schema," i.e., over the web 
languages already being developed and used.  and the solution of a 
white paper, while valuable, in my opinion must be combined with a 
short and to-the-point (e.g., one sentence) answer to the question.

when i have asked various people variations on this question, i have 
gotten long answers, good examples, language constructs in DAML + OIL 
that are not in XML + ..., etc.  but what i have not gotten, and i 
could seriously use in my current dealings, is a straightforward and 
short explanation of the value added.  the scientific american 
article, and many other documents, give great explanations of what 
good the semantic web is, which the naive person (who, for instance, 
only knows XML or HTML) buys, but the sophisticated person who knows 
RDF and all the W3C work is harder to convince without this clear 
value-added statement (especially if he is cynical or doesn't want to 
be convinced, like the people i am dealing with now).  he can be 
convinced with much more info, such as in the white paper david 
suggests, but i still think a one-liner would be valuable to get him 
to read the details.

just my 2 cents.
