Re: update to wiki on web accessibility basics

Hi all
I have updated section 2.1, 2.2 and 2.3 of  the webed wiki

> * http://www.w3.org/WAI/EO/wiki/Web_Accessibility_Basics
>

This wiki material makes use of information from the 'how people with
disabilities use the web suite' to develop an easy introduction for
developers to this material.

There was some confusion as to the intuitive meanings of diversity OF web
users and diversity IN web use so I have created two distinct subsections
to clarify that one is about  disabilities and the other is about tools and
strategies.

I may not be available on Fridays telcon, so I would like you to consider
two issues:
I would like the disabilities section (2.1)  to address the common
misconception that being blind is the only disability affecting web use.
Should this be made more explicit?

 Another common misconception (I think) is to become locked into a medical
model of causes and symptoms. I would suggest that the web developer just
needs to know about the consequences that affect web accessibility. Should
there be an explicit reference to the social model - or just the functional
effects in what I would like to call  the 'engineering model'.

I will also contact the EO editors to see if there is time to change the
heading titles of 'diversity in web use' into something more intuitively
leads to tools and techniques.
