Dumbing down your web site content
The Oxford English Dictionary says ‘dumbing down’ is: ‘simplified so as to be intellectually undemanding and accessible to a wide audience.’
The most important word in that definition is ‘accessible’.
If you make your content easy to read, you aren’t ‘dumbing down’, you are opening up your information to anyone who wants to read it. You are making it accessible. You are trying not to exclude people based on their education, cognitive function or reading ability.
