the page i rated is my joyce overview:  http://www.robotwisdom.com/jaj/

and it's my showpiece of applied info-density theory, so i recommend you
look at it before sneering.

I don't follow any of the meandering, off topic, replies to 
date, John. So I'll just barge straight in and be as clear 
as your goodself.

It seems clear to me that the 'umbrella-concept ' under 
which your site operates is minimalistic and structureless 
information'.

Absolutely agree. Three licks shold get any visitor to any 
element of content they seek.

The problem with your style is that you are not optimising 
anything.  What you are doing to stripping the content of 
all structure and focus. Human communication is not the same 
as computer or robot communication - as much as you may wish 
that it were.  Human communication depends on shape, form, 
focus, hierarchy and digestibility. Your theory and site 
lack of these elements. It may be efficient in 
communciations information quality down a telephone line - 
but it is not efficient as communicating information to a 
human being.

Your site lacks summaries, simplicity.  There are NO images 
despite your definition.  A link such as 'service like 
Atomz.com ' cannot be described as clearly described.

The problem with your approach is that it is as inappropriate 
and pointless as the graphic artist gone mad approach.  One 
end of the spectrum is obsessed with everything but the 
content - while the other end is obsesse with everything but 
the presentation.

Both approaches are doomed to dismal failure in the face of 
human communication dynamics which demand a balanced, 
stuctures and focussed approach for any kind of success to 
result.

Few visitors to a site are so single minded on obtaining the 
information on 'that' site that they want to do nothing 
other than read 5,000 information-packed words on the 
relevant topic. The vast majority of site visitors are 
seeking bite sized chunks of information that may or may not 
be present in the site being visited.  They do not wish to 
read through 5,000 words to come to the conclusion that the 
chunk they seek is not after all there. 
And most of the rest of the visitors are not seeking any 
specific piece of information, per se. They simply wish to 
get a 'flavour' of the content.
In the realms of the commercial site, your approach is a 
suicidal 'trip' for any prospective business.  In the realms 
of the reference site, your approach is guarenteed, imho, to 
bore the pants of any inquirer.

[another snip]

All of this smack's of Jakob Nielsen's ideas on
usability on the 'net (and his book "Designing
Web Usability).  I have some disagreements with
his theories as well, but he does balance
"information density" with usability.

I mean, what if I removed all the paragraph
breaks, graphics, and white space from a
document?  The whole page would be one clutter of
text: tons of information, but hardly usable.

As opposed to reducing the file size (which
Nielsen also does, across the board), there's
also the "screen" size.  Perhaps no more than 10%
of the  screen should be devoted to navigation,
for instance.  Of course, a 640x120 navigation
bar is only 10% of a 1024x768 screen, but is over
25% of 640x480.  So good luck there...

I highly recommend reading up on usability as a
whole, as opposed to narrowly defining success in
terms of "information density."
