Today, we're testing a new design that bubbles up more of the information flowing through Twitter. This builds on a series of changes starting last year when we redesigned the homepage to make search and trending topics more visible and easily accessible to everyone. With the new design, we're intentionally featuring more dynamic content on the front page, revealing a sample of who's here, what folks are tweeting about, and the big topics that they're discussing. The homepage now features a set of algorithmically-selected top tweets that automatically appear every few seconds.
