Openness
Openness on the internet or the web refers to the ability that anyone with access to the internet has to post or create something and share that with others. To read more in depth about internet accessibility check out The Internet Policy Review.
Why?
Making open content allows your creation or whatever it is you decide to post reach the largest amount of viewers. This can seriously inspire other people working on their own passion projects or simply help someone fix a common household problem.
How?
Making open content and sharing it on the web can be as simple as making a public twitter post or uploading a tutorial video on Youtube. However, you can also use openly available content to make a profit, such as by running advertisements or sponsorships on your video.
Accessibility
Accessibility is ensuring that the content you create or share publicly is available and usable by the most amount of people possibly.
Why?
Ensuring content is accessible to the most people possible is important from a moral but also a more pragmatic side. First of all, content should be accessible because it is the right thing to do, providing informative or other forms of content should not be restricted based on any kind of disability. Secondly, many countries, such as the United States and Europe, require content to be accessible to at least a certain standard mandated by law. Failing to follow these guidelines can result in legal action. But, making your content accessible shows that you took the time and effort to go through the steps to ensure accessibility resulting in a gain of goodwill from the public.
How?
Tools to ensure accessibility can include things like the use of headings to accommodate those using screen readers or by including alternative text on image. For further visual mediums, like videos or games, the use of subtitles or the inclusion of a color blind picture mode can greatly increasing accessibility to those programs or services. These features are also very useful to people who do not necessarily need them, but find them helpful regardless.
