It’s most outward feature is a font size and color contract toolbar that helps users more easily read your content. But it also does a lot of behind-the-scenes work like adding skip-to-content links, implementing an outline to the link :focus state for better keyboard navigation, utilizing longdesc for images and a whole lot more. Each feature can be turned on or off through a settings page.
more than the list of websites, I appreciate the 10-second method you describe. I think it's worth explaining to developers and site owners that there are indeed some simple tricks to quickly assess a web page without having a deep understanding of the WCAG. Personally, I like removing all the CSS styles (with the Web Developer Toolbar in Firefox, shortcut is Shift+Ctrl+S). If the page is still pretty readable, with no clumsy technical code; if it shows a neat heading structure; if lists appear well structured and appropriately used; if all text, is in black (except links), left-aligned, and with its default font and size; then it's been probably properly coded, HTML-wise.
The Federal Communications Commission (FCC) enforces regulations covering telecommunication services. Title IV of the ADA covers telephone and television access for people with hearing and speech disabilities. It requires telephone and Internet companies to provide a nationwide system of telecommunications relay services that allow people with hearing and speech disabilities to communicate over the telephone.

This particular lawsuit amounted to nothing more than a shakedown for cash, as the current laws would make it difficult to win the suit in court (more about this later) but it prompted me to dive deeper into the issue of ADA compliance. Through my research, I discovered there are some new laws on the horizon that could make ADA compliance mandatory, which means web designers and digital marketers need to know how to prepare.

The free nationwide telecommunications relay service (TRS), reached by calling 7-1-1, uses communications assistants (also called CAs or relay operators) who serve as intermediaries between people who have hearing or speech disabilities who use a text telephone (TTY) or text messaging and people who use standard voice telephones. The communications assistant tells the telephone user what the other party is typing and types to tell the other party what the telephone user is saying. TRS also provides speech-to-speech transliteration for callers who have speech disabilities.

Video remote interpreting (VRI) is a fee-based service that uses video conferencing technology to access an off-site interpreter to provide real-time sign language or oral interpreting services for conversations between hearing people and people who are deaf or have hearing loss. The new regulations give covered entities the choice of using VRI or on-site interpreters in situations where either would be effective. VRI can be especially useful in rural areas where on-site interpreters may be difficult to obtain. Additionally, there may be some cost advantages in using VRI in certain circumstances. However, VRI will not be effective in all circumstances. For example, it will not be effective if the person who needs the interpreter has difficulty seeing the screen (either because of vision loss or because he or she cannot be properly positioned to see the screen, because of an injury or other condition). In these circumstances, an on-site interpreter may be required.

The Americans with Disabilities Act (ADA) was first passed in 1990. Twenty years later, the US Department of Justice released an update called the 2010 ADA Standards for Accessible Design. These standards cover the design of physical spaces and have been interpreted to include web locations as well, so it can be difficult for the would-be accessible website designer to use them.
