Re: (emacs) Intro [was: Making Emacs popular again with a video]

[excalamus]

Is this something I should continue investing time in?  

Before posting a revision, I've been awaiting feedback on:

* What *defines* an Emacs? Is it "the Emacs idea", as I've called it, that each 
key press is transparently associated with a function?

* What sets GNU Emacs apart, specifically, from other Emacs?

* Did I clarify the reasoning behind the sections that caused confusion?  I 
intend to revise those sections and want to be sure that their focus is correct 
and that it is the merely the wording, and not the purpose of the section, 
which needs revision.
