WikiHawaii which means "fast". This word is now used on the internet (see net jargon) as a name for a kind of website -- like Wikipedia -- that lets any person change a page. Like this, pages can be changed often and if a person writes something false, it can be fixed quickly and easily. This only works if all people are working toward the same goal.
It also means that people who have different ways of thinking (opinions) other people don't have can keep coming back and keep changing the page to say only what they think.
In theory, more people can fix mistakes. In reality, they may care about something less than needed, or they may be scared to fix things.
