There is one problem, which is that user agents incapable of showing the original element's default style (e.g. a text mode browser with no font size control, or a speech browser, or a braille browser) has no guidance as to what to do with the contents. On the other hand, using a semantic element like <em> allows the user agent to intelligently substitute the original recommended rendering with an equivalent rendering that it can render on its medium. > The problems of the past arose because: > > 1) people used the wrong semantic elements > 2) people used non-semantic elements where there were semantics > > In the above scenario, there are semantics, but there are no semantic > elements to convey shouting.

Mathematics are indeed a thorny problem. It's unclear that <big> would go far enough in solving it though.

In HTML5 <em> and <strong> are orthogonal in definition.
