It's an HTML4-ism. In compliant browsers it displays some variety of text decoration with the marked up text. In Mozilla, it's a dotted underline. In IE5 Mac, it's a dotted underline + small caps.
I have NO idea why we're using it - it's the wrong tag for the purpose. The title attribute can go anywhere in proper HTML - it provides descriptive text... IE 5.5 & 6 as well as Mozilla use this as the tooltip text.
