tells us that quite bearable: "This page has an average grade level of about 7. It should be easily understood by 12 to 13 year olds."
But I honestly do not like such "style". One time I tried to use a browser extension that improves readability the desired website, but due to the fact that it was perepechatyvali in approximately this format, removed.
Apparently, subjective and a matter of habit.
