Yesterday, Twitter's Ev Williams announced a completely re-engineered Twitter.com to provide "an easier, faster, and richer experience. The familiar timeline you're used to seeing on Twitter.com is still visible, but underneath each tweet is more information, context, and sometimes embedded photos or videos. Clicking a tweet provides a slide-out pane containing the additional content.
Additional highlights of the new Twitter, as explained in an official blog post include a new, cleaner design that minimizes clutter on the home screen but provides more detail for each individual tweet; easier access to embedded media like photos and videos from a variety of hosts like Flickr, Vimeo, YouTube, yfrog, and more; and easy access to related content like @replies, other tweets from that user, and a map of where a geo-tagged tweet was posted.
Find out when to expect a change to your Twitter account and check out a beautiful explanatory video after the break.
The changeover to the new Twitter will begin as a preview tonight for a small number of registered users, and continue over the next few weeks as changes roll out to all users. For a limited time, you'll be able to switch back and forth between the old and new versions before the changes become permanent.
