Isn't that a bit like saying "If you ignore the email part of GMail..."? 
In any case, without purchasing, one can write reviews, rate products, 
etc. So there is certianly an ability to manipulate data. A web forum is 
also a type of web application with similar functionality (indeed, these 
have superceeded news readers in many environments).

I understood that it was the web application itself that ws consuming 
the markup, not the UA. Your original example was a web-application 
based RSS reader. In this case, the UA has no need to ever come into 
contact with the RSS, just with the HTML (or XForm or XUL or whatever). 
Similarly with an internet based mail app; the user (or UA) has no 
interest in the format of the email, just with the data avaliable at the 
app-end.

As a user I know the from address because it has the string 'from:' 
before it (or some other such thing). Now that's not enough that I can 
trivially scrape GMail and export the information to a standard mail 
client (the use case you seem to be proposing) but, in most situations 
that's not what I want to do; I just want to read my email. Moreover, in 
many situations that's not what the service provider wants me to do 
either. So if your application-level semantics were ever avaliable they 
would most likely go unused by most developers. The problem for language 
design is that there's no way to provide those semantics for every 
possible format of information that one might want to transmit. RSS/Atom 
can deal with simple weblogs but if I syndicate lists of recently 
published books (say) they have no relevant semantics. So what do I do? 
There's not going to be an existing langauge that meets my requirements 
so I have to invent one. At the point that I've invented a language, 
semantics are irrelevant because no general purpose client application 
is going to know them anyway.

You have been around the list enough to know that "HTML 5" is the 
half-joking name that has been bandied about by list members for Web 
Forms 2 + Web Apps 1.0 which are avaliable in the usual place. Is there 
a good reason for the feigned ignorance?
