I'm of course not saying you can't come up with more natural sounding
renditions.  The question is how this can be done in a principled
fashion.  Note, for example, that you are using "kissed" in such a way
that, first, it allows the auxilliary "has", and second, the prounoun
referring to the person kissed is deleted.  So we need some sort of
explicit grammatical transformation that tells us precisely when such
deletion is permitted.  I fear your idea will require a full-blown
transformational grammar of some ilk.

No good; the denotation of "her" is ambiguous between the two girls.

Again, the problem is how this could be accomplished in a principled
fashion.

Ditto.  Anybody can come up with more readable English.  You need a
completely specifiable grammar for generating this more readable
English if you are wanting a useable product.

Okey doke, fair enough.

So what?  "better" means nothing more than those who actually bother
to learn the material.  I don't necessarily mean "smarter".  I just
mean that they are better in the ways one must be in order to perform
well.

Nothing follows about elitism.

The number here is meaningless, as we have no clear sense of the
connection between number of neurons and general intellectual
capacity.

I've agreed that it is important to provide the resources needed to
understand the SUO.  I just question your approach of faux-English as
being the best resource.

I find this view utterly bizarre, but would always be willing to hear
the argument; I can't begin to imagine what it might be.  But you are
right that this is not the proper forum.
