"Legalese" is for lawyers. They write the way they write because there can't be a fragment of ambiguity when it comes to an altercation with the law. I'll take legalese protecting my business any day of the week. But it sucks that it has to be so difficult to read. It's not that the words don't make sense, it's almost that they make too much sense. It can take paragraphs and paragraphs to say something a human would say to another human in a sentence or two.
Take this example:
As a condition to your use of the CodePen Site, you agree not to upload, post, email, transmit or otherwise make available any information, materials or other content that is illegal, harmful, threatening, abusive, harassing, defamatory, obscene, pornographic, offensive, invades another’s privacy, or promotes bigotry, racism, hatred or harm against any individual or group.
We all know what that means:
Don't be a jerk.
The second is a lot more readable, no? And that section of legalese is actually one of the more readable passages.
