Accessible websites are usable websites. Web pages can be designed to be understood by access devices such as Braille readers and screen readers. Well constructed sites that do this are structured so that they also work efficiently on other devices such as mobile phones and handheld computers.
In the future, there are going to be many different ways to access the internet. Organisations who consider this now are going to be prepared for the time when everybody is carrying a Blackberry or similar device in their pocket.
A website has a far greater reach to all users if the designer builds it with disabled users in mind. That needn't be at the expense of design. The Go2ten website conforms to the World Wide Web Consortium's (W3C) accessibility guidelines.
Tim Berners-Lee, W3C director and inventor of the World Wide Web, says, "The power of the web is in its universality. Access by everyone regardless of disability is an essential aspect."
Tenets of the W3C's guidelines include consistent navigation and giving the user the ability to change font sizes. All users will find such a site more accessible. In reality, web accessibility is simply the ultimate in web usability.
