So Web Services has ambitions to be as successful as the Web in a few
slightly similar ways.  I don't think that establishes much meaningful
connection.

And that usage is one of the most widely criticized aspects of Web
Services in their present form, as that usage diverges quite strongly
from "Web" usage of URIs.  Reuse of HTTP URIs is a particular problem,
one that helps identify Web Services' serious incompatibility with the
Web.

I prefer that we find some criteria which define the Web as something
separate from the Internet in order that these conversations might have
some shared foundation on which to arrive at useful judgments.
