Since the mid 1990s, when web accessibility first emerged as an unarguable concern, ideas and attitudes have evolved to a point where we understand a great deal about not only the technicalities but also the psychology of achieving true accessibility. This evolution of ideas means methods first proposed as ideal solutions for accessibility are now outmoded and no longer provide the sustainability required by content rich web sites and ever widening audiences. Once it was deemed satisfactory to design a web site with unrestrained visual creativity and simply append a text only alternative site to bridge the gap to accessibility. This is no longer necessary.  The technology now exists to design a single, visually engaging web site that can be accessed by everybody. Moreover, the importance of considering human nature in achieving this has now propelled web accessibility into a field combining a surprising variety of disciplines. The reasons for choosing this single site approach are not legion but they are compelling:-
- Cost Effectiveness;
The case for removing the distraction of a text only site is profound. The task of attempting to sustain two sites, each on an equal footing, is wasteful of both time and resources. It may also be to the detriment of the organisation's reputation. Demographics clearly indicate that the percentage of people using a text only site will be significantly smaller than the mainstream audience. This means that the majority of traffic will pass through the primary site, generating the most revenue and interest. The logic is therefore to allocate considerable resources to sustaining the site that is driving the organisation forward most effectively, but the inescapable consequence of this is the demise in quality of the secondary site. If the dual sites cannot be sustained with equal vigour and resources, the discrepancy in quality merely grows to a point where the text only site is an appendage without purpose or integrity. It is far better to opt for a single site from the inception and to focus development and effort into sustaining it as a singular example of the brand it represents.
The brand factor is key to the decision of whether a single or dual site approach is appropriate. It may be believed that an organisation who provides a text only site is acting altruistically. However, when viewed by someone who is compelled to use such a site, the perspective is starkly different. In our recent past we have impelled people to use different services on account of their race and we have insisted that they do different jobs on account of their gender -- we have now come to recognise the error of our ways. Now that the technology exists to offer a single site that is accessible by everybody, do we really want to suggest they use a different one on account of their disability? It is at the very core of humanity to belong to a community. Whether it is a football team, a group of pub regulars or afficionados of a television series, we all band together because we like to feel included. No one likes being excluded, and understanding this is a powerful tool in web accessibility. An organisation that manifests this understanding by choosing one site for all people will benefit from an enhanced brand reputation. In our multicultural society the need to embrace all potential Internet visitors is a requisite for an organisation that aims to be forward thinking and successful. The very people who are assumed to benefit from a text only site would prefer not to use one.
It can all be reduced to a very simple argument. If an organisation is serious about their reputation and quality of service, if they want to be cost and resource effective over a sustained period of time and if they want to be an example of social responsibility -- the single site approach is simply the only choice. 'One for all and all for one!' - Alexander Dumas, 1884.
