My own small 2-cents worth:

I kind of agree with Warp--the essay pretty much jumps right in with a rather
technical discussion.  A GOOD one, of course--very well done!--but it needs a
short preamble, IMO, to get folks up to speed on what gamma is basically about
(as pertaining to *images*, which is what most of us first become concerned with
when doing CGI.) Perhaps something simple about how gamma basically bends the
color/grayscale values of an image, while leaving pure black and pure white
untouched. *Then* getting deeper into the technical aspects of CRT/LCD
reproduction, etc. I agree that part of the first paragraph, "...regarding how
intermediate brightness levels between 0% and 100% are interpreted," pretty much
says it all; but it doesn't quite grab me, or give an immediate picture in my
mind of how it basically affects images.

The best advice I ever heard about writing in general was, "Grab 'em right from
the start! Make it simple! Then they'll stick around for the details."
