I honestly believe that's the least of our worries. How often do you
need to determine whether something in the universe of discourse is an
electronic document or not compared with all the other questions you
might be asking of your data. I might conceivable ask "show me all the
documents about this toucan" but I'd much rather ask "show me all the
data about this toucan"

That's true. I don't suppose any of the big crawlers care about the
semantics of 303 because none of them care about the difference
between a thing and its description. For example the Google OpenSocial
doesn't give a hoot about the difference and yet seems to still
function. As I say above, this document/thing distinction is actually
quite small area to focus on compared with the the real problems of
analysing the web of data as a whole.
