What does "get" help identify in that URI?  What if I want to invoke PUT
on that URI, do I still need the "get"?

URIs and HTTP work together when HTTP provides the methods, and URIs
provide the identifying information.  As soon as you try and make
one do the job of the other, you run into all sorts of problems.

A URI is like an object reference.  It's just a pointer.

'fraid so. 8-(

Would you consider building application semantics on top of
getStockQuote()?  If so, what would that look like?  I've used this
example before, to show how odd that would look;

String weather = getStockQuote( "getWeather( 'Ottawa' )" );

That's called tunneling.
