Accessibility is something you must do—most importantly because it’s the right thing to do. Accessibility is about making sure everybody can access your content.

Think about it. There are large numbers of people, whole segments of our population that have various degrees of ability and need to access information in different ways. Vision impaired people for example may use a screen reader. There are many people who can’t use a mouse and need keyboard shortcuts or other means to browse the web.

In the US it is law (referred to as Section 508) and you must follow it to do business with the US Government. In Canada it is recommended practice and we have guidelines.

By taking a web standards based approach you can go a long way towards meeting these guidelines.

Not to do so is shortsighted and just plain wrong.
