Roger Johansson looks at how popular services, like Blogger and Bloglines, assume availability of JavaScript. If you try explore the reasons behind unavailability, you will end up looking at the security model of JavaScript. Most of the corporates, and a lot of individuals I know, either disable JavaScript or block it partially for security reasons. Because of this, not abiding by the best practices of JavaScript can lead to a non-accessible website. Even if it means more effort, do not plan on using JavaScript or dependent technologies like AJAX without looking at progressive enhancement and graceful degradation.

Perhaps this is why I can’t access my Bloglines feeds at the public library’s computers. Quite possibly they have disabled Javascript. They use IE for their browsers, but if I remember correctly, it wasn’t even IE6, but 5 that was installed. So I always thought it was antique software.

It is common to disable JavaScript or block it partially in organizations where various users can visit various sites. It is easy to provide an alternate implementation when it is disabled, but it becomes difficult to make it work without loss of user experience when it is partially blocked.
It is scary though that they are using such a old version of IE. They need to upgrade or move to other browser.
