Third-party applications and customization features take center stage on Yahoo’s new homepage as the company rolled out the beta version of its redesign for U.S. users Tuesday. Actually, “center stage” isn’t quite accurate; the long list of colorful icons for Facebook, MySpace, eBay and HotJobs, along with Yahoo’s homegrown services like Mail and Messenger, can be found on left-hand side of the new home page. Users can add or subtract the apps they want to see on Yahoo’s front page, or can take the suggestions offered in a recommendations section at the bottom of the list.
