At some point, having a well-known set of URIs for referring to 
common concepts will be very useful. It isn't clear to me whether 
we're at that point, but I suppose that depends on what set of 
concepts you're talking about identifying.

First, is a new URI scheme really necessary? Why not use URNs?

Second, I have to say that I'm not yet convinced by TBL's argument. 
It seems to me that I can easily assign a URI to my car (eg, 
<http://example.com/my/car>) and other URIs to documents describing 
my car (eg, <http://example.com/my/car.html>, 
<http://example.com/my/car.jpg>) and use content negotiation and the 
Content-Location header to return an appropriate representation if 
someone happened to dereference <http://example.com/my/car>.
