The most recent issue of "Internetworking", the newsletter of the 
Internet Technical Group, has a couple of very useful and interesting 
articles.  Here are abstracts and URLs:

"Banner Blindness, Human Cognition, and Web Design", 
 Donald A. Norman.

 http://www.sandia.gov/itg/newsletter/mar99/commentary.html

This is a follow-up to an earlier study by two Rice University 
researchers, which came to the counter-intuitive conclusion that if 
you want to draw primary attention to a link on a web page, about the 
worst way to do so is to make it a large, conspicuous graphic.  

Their thesis, echoed and refined in the follow-up cited above, is 
that users have in their minds a schema as to how a Web page "should" 
work, of what is likely to be a link and what isn't.  And most often 
links are pieces of text, in list form, offset from other elements on 
the page. Thus, as we scan a page our eyes are drawn to elements that 
seem most likely, based on previous experience, to be links; we 
reflexively ignore large graphics that do not seem likely to be.  

This is obviously a little ironic and unexpected in some ways -- 
quite literally, the study showed that the larger and more 
conspicuous the graphical link, the more likely it is to be ignored 
and/or misinterpreted.  Chalk up a point for the "HTML purist" camp 
<g>

(I've noticed this phenomenon often myself, actually.  Just the other 
day I was looking for the latest on Melissa at C|Net, and was amazed 
to see that they apparently had nothing about the arrest of that dim 
bulb in New Jersey.  There was a long list of text links to other 
"Top Stories", but no mention of the bust.  It was only after 
studying the page carefully that I realized the story had its own 
graphical link, quite large and colourful, at the top of the page; I 
guess my mind just discarded it immediately, associating it with the 
banner ads and other superfluous junk up there.  At any rate, I 
didn't see it.)

"Separating Content from Visuals in Web Site Design", 
 Jeanette Fuccella and Jack Pizzolato

 http://www.sandia.gov/itg/newsletter/mar99/wireframe.html

This article I found quite intriguing because it just happens to 
recommmend an approach to site design that I've stumbled upon myself 
in recent weeks: separating the content and structure from the 
graphical elements throughout the development process. 

The authors contend that melding the two right from the start only 
serves to distract both developers and testers from making worthwhile 
decisions on the usability of the content and structure, because they 
tend to become preocuppied with the aesthetic appeal of the graphics.

Instead, the authors recommend that you create two parallel forms of 
the site: the first a "wireframe", containing only the text and 
navigational links, the second a graphical dummy with greeked text.  
The idea is that testers will be focussing *only* on the content in 
the one case, and *only* on the look-and-feel in the other.  As you 
identify approaches that seem to work for each, you can begin 
integrating the content and graphics towards the end of the 
development process, resulting in a more cohesive and functional 
final site.

I've been taking a similar approach with my ongoing redevelopment of 
the Bank's site, based on past frustrating experience.  I'm sure many 
of you have been through something like this: 

You sweat blood for several weeks restructuring and rewriting content 
for a client's site, and to a lesser extent developing suitable 
graphical elements... then when you demo the site to the client, 
expecting him to be duly delighted with how much more logical and 
readable his content now is, he says, "Hmm, I don't like the shadow 
on that 'Search' button.  And can you make that blue border match our 
corporate Pantone colour?"  Sigh.

Anyway, so at the office I'm doing my development work totally 
graphics-free for now; all the emphasis is on the content and 
structure, which I want to have totally nailed down before I start 
adding the final touches, graphics in this case.
