We create things on the internet so that people can access our information and, often, so that we can get information from them. Unfortunately, we often overlook difficulties and differences that people have when accessing our content, which is ultimately pretty self-defeating. We need to be able to empathize with our users, and make sure our content is accessible to as many people as possible.
