My Yahoo is a customizable start page that users can fill with a variety of personalized content feeds. Like some other single-page aggregators, My Yahoo centers around its directory, which is filled with all sorts of feeds--some from third-party sources, while others are in-house Yahoo content. People can mix and match, move things around, and custom-tailor their page however they please.
In addition to content, users can also pick from a wide variety of themes to decorate their page. Each of these themes can be customized, including color and font.
