The Justice Dept. said it would issue new regulations, so most businesses waited to see what they would say. However, Vu believes it will be a while before the new regulations are released because of what the Justice Dept. said in a recent case. MIT and Harvard were sued over captioning of videos, and the schools wanted the judge to stay the case until the new regulations were released. The Justice Dept. told the judge not to stay the case because the new regulations could take a while to be released.
Use the plugin, follow its instruction, and resolve the compliance issues identified. You’ll find that using the plugin will save you an incredible amount of time as you maintain your site’s compliance on a month-to-month basis. The best part, it identifies the compliance issues and tells you exactly which code elements are out of compliance and why! Our average customer is reporting a 10x-20x time savings over manually identifying and fixing these problems. In extreme cases more than 30x time savings has been reported! Using the plugin alone does not guarantee compliance. Some parts of accessibility can’t be automatically scanned and must be manually audited but we also provide independent 3rd-party audits and certifications of compliance. The Accessibility Suite Pro Plugin for WordPress makes this process profoundly easier.
...the full and equal enjoyment of the goods, services, facilities, or accommodations of any place of "public accommodation" by any person who owns, leases, or operates a place of public accommodation. Public accommodations include most places of lodging (such as inns and hotels), recreation, transportation, education, and dining, along with stores, care providers, and places of public displays.
@Rick, I didn't specifically look at doctype, but Steve Faulkner did in his original article (see the link at the top of this post). He found that 101 of the 130 pages containing role="main" (78%) used the HTML5 doctype, which of course leaves 22% that didn't. I do recommend using ARIA even if using an earlier doctype. Validation is important, but if validation and accessibility conflict, I think most would agree accessibility should trump validation. Assistive technologies that support ARIA landmarks do so regardless of doctype, and otherwise the presence of these role attributes has no ill effects in any user agent.
Luckily, the international nonprofit World Wide Web Consortium (W3C) brings together smart people who develop open standards to ensure the long-term growth of the Web. They produce recommendations for making websites fair and equally accessible for the highest number of people possible. Their Web Content Accessibility Guidelines (WCAG) 2.1 offer clear guidance for web developers to achieve ADA compliance.
When you insert an image into a post or page, consider providing a rich description for the caption that will improve the reading experience for everyone, but especially folks who can’t see the image. Be creative. Instead of “My son on his swing,” try “My son is playing on his favorite swing. His face is filled with pure joy on a beautiful Spring day. Perfection.” The goal here is to convey the feeling of the image. 

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.
When choosing an aid or service, title II entities are required to give primary consideration to the choice of aid or service requested by the person who has a communication disability. The state or local government must honor the person’s choice, unless it can demonstrate that another equally effective means of communication is available, or that the use of the means chosen would result in a fundamental alteration or in an undue burden (see limitations below). If the choice expressed by the person with a disability would result in an undue burden or a fundamental alteration, the public entity still has an obligation to provide an alternative aid or service that provides effective communication if one is available.
The ADA requires that title II entities (State and local governments) and title III entities (businesses and nonprofit organizations that serve the public) communicate effectively with people who have communication disabilities. The goal is to ensure that communication with people with these disabilities is equally effective as communication with people without disabilities.
