WebHint is like a tooltips-type help systems introduced by Apple Computer in their System 7 operating system release. The name referred to the way the help text was displayed, in "balloons", like those containing the words in a comic strip. The name has been used by many to refer to any sort of pop-up help text. Developers were encouraged to include help text with a certain grammar, and not only the object name being looked at, but also explanation of any state it might have to the user. For instance, modern tooltips might say something like "copy" to explain a button, but our web UI control component suggests the more detailed "Copies the selected text onto the clipboard". Balloons are far more helpful than modern tooltip systems, and help users to learn more.
