Reading through this article, there wasn't anything dramatic  or revealing 
which was not known and hence would make any difference to us, as claimed, 
following the research.

The solution suggested is also well known and is of common knowledge.

> information
> sciences, has been conducting research with the National Federation of the
> Blind to change Web design.
> In Lazar's research, 100 blind or visually impaired Internet users
> volunteered to document all of the frustrations they encountered while

> Wide Web.
> This is one of the largest studies of blind computer users ever 
> undertaken,
> according to Lazar.
> "Most studies have only five to seven volunteers," he said.
> Lazar found that the volunteers had many frustrating concerns.
> "Most of the problems found for blind users were technically easy to 
> solve,"
> Lazar said. "Will it take a lot of time? Yes. But technically it is easy."
> There are a number of software programs for blind people to use the 
> Internet
> such as Jaws and Window-Eyes.
> "These programs use audio technology and are known as screen readers," 
> said
> Lazar. "They are strictly using audio."
> These programs help users navigate Web sites by reading through all the
> material on the site. For example, when browsing through a Web site, while
> having
> a screen reader program on the computer, the program will read off 
> whatever
> information is in the heading of the site and then list each of the
> following
> links to the user.
> "Essentially it reads any text and backend code," said Lazar.
> Lazar said that one of the problems with the Internet use among the blind
> stems from Web developer's faulty designs. He said that Web developer's
> leave
> out descriptions for each link that screen readers would normally speak
> "Some pages are misleading, while others don't work at all," Lazar said.
> The study found that the Web developers for many sites do not label links 
> in
> a way that screen reader programs can easily communicate to a blind 
> person.
> Lazar said this is an easy fix to correct for those Web sites, but it does
> take time. For example, when tabbing to different links and boxes on a Web
> page,
> a computer user might highlight an image on the site, but instead of
> describing what the image is, it might say, "click here" when selected.
> "This just doesn't do you any good," Lazar said.
> He said it is all a matter of spreading awareness to the Web developers.
> Lazar, the NFB, and numerous other organizations are working toward 
> training
> Web
> masters.
> "We need the Web masters to spread the word," Lazar said.
> Lazar said he hopes his conclusion of his research is working and that Web
> developers will see the need for better design and coding in Web sites.
> "Not all are convinced that accessibility is important," Lazar said. "The
> key is informing people."
