Twitter is rolling out a new version of its interface today, shuffling around all your information and compartmentalizing it into four distinct elements: Home, Connect, Discover, and Me. The interface is completely redesigned on the web, and comes along with updated versions of the company's mobile apps. It's clear that this marks a major initiative for the company to bring together disparate parts of its service, not only in web views, but to connect the dots between its online and app presence.
As you can see in the photo above, the basic interface has been significantly streamlined, and is now putting more focus on not just @ mentions, but "activity" across your network, including who has followed you, favorited a post, and more. This goes in line with the activity view which was rolled out just a few months ago.
Additionally, the mobile apps have been redesigned (quite handsomely) to reflect to web changes. You'll find a similar stream of activity there. Android and iOS users can get the new version right now. iOS users may not immediately see the update, but can grab it by going to the App Store > Updates > Purchased. We checked out the Android app on Hoenycomb, and the new version hasn't added any screen size optimizations. It's still the same mobile app, stretched to fill the larger screen.
We're working on a detailed hands-on of the new experience and apps, and will update accordingly.
