I really don't like it, for one. I don't see the SW as being in a 
layer above the Web, and the only way I can make sense of this seems 
to suggest a misunderstanding of the aims of the SW; that is is 
supposed to be in some sense a new kind of meta-data about the Web 
itself.  If y'all have that idea in mind, please try to put it out of 
your mind. SW technology *could* be used that way, but that is not 
the primary or intended use case for the technology.

BTW, the current usage of "resource" in the SW specifications is 
vacuous: a SW Resource can be anything whatsoever, real or imaginary, 
on or off the Web, in the past or future, of any nature, with or 
without a URI. So to claim that all SW resources 'contain' a Web 
resource sounds like it would also have to be vacuous or else would 
be obviously false (depending on what a 'web resource' is, which of 
course I have no idea about, this never having been defined or 
elucidated anywhere.)

I have no idea what an interface to an object could possibly be. 
What kinds of interface do the following objects have: a grain of 
sand, a galaxy, an imaginary detective ?

PS.  Reading things like this makes me wonder whether you guys 
inhabit the same planet as the rest of us. Things with hearts and 
multiple interfaces, arranged in layers...?? What the hell are you 
talking about??? Here I am looking out of my window at an oak tree 
and I wonder if its a resource, and what its interfaces could be, and 
what layer it would be in.... and then I decide that none of this 
makes the slightest sense. Unfortunately, that is the only conclusion 
I am left with, yet again.
