Re: How many people switch off javascript?

Another arguement is that people are using a wider range of
technologies to access the web. Designing using standards and
markup that can adapt a wide range of technologies and user
needs makes their website more flexible and compatible with
new technologies. Some people call this "forward Looking
Design". One major example is dot pitch on computer monitors
is getting smaller (more dots per inch of screen). Web pages
that uses images for styling and pixels for layout of content
are slowly shrinking in size, whether you have a disability or
not! So one arguement is you need to have web resources that
can easily adapt.

You could also argue that instead of worrying about pull down
menu, put the money into usability testing to see how real
people use the site and optimize the user experience.

Here is a link to a "Best Practices" document we are working
at UIUC on implement what we call "User Centered Web Design".
