Sounds do ; Flash do. It is at those elements that lengthen page load times. Overuse of graphic buttons rather than pure text also does - and limits accessibility.

After that there is the matter of taste ; graphic designers and typographers recommend limiting font use to at most three on a single page...

And the more different elements are incorporated into a page, the harder it is to do tastefully, too. Simple design avoids horrible results - and it seems we are a bit short on professional designers here, halas.
