Setting font sizes by relative terms: GOOD.

People have set the font on their browser to be the size that they can read the normal text without having to adjust the size. This should never ever be redefined; that is, what makes up the 90% of the page text should be unstyled in terms of fonts and colors and use the user's options as specified by the browser. If you play with the font size, even by setting pt to be nice across platforms, you'll anger people that try to read sites at 1600x1200 with your fixed 8pt font that looks great at 800x600.

Any font changes should be specified in HTML tags using <BIG> or <SMALL> tags, or in CSS using font-size: smallest | smaller | small | normal | large | larger | largest. But, IMO, I only specify font sizes on footnotes and the like; any normal text remains at the default size.
