I definitely agree with you on that.

A sufficiently smart application that crawls your Web site will not just
record
[Bush wonThe Election]
The fact that this statement exists does not add anything to what we
already know.
Rather, the app will store something like that:
[[Bush wonThe Election] isSignedBy <Seth's cryptographic signature>]
or
[<Seth's URL> contains [Bush wonThe Election]]
For the above scenario, I don't see the need to Skolemize more than a
single statement.
