It's Christmas! Facebook Timelines and now #NewNewTwitter

Twitter- Yours to discover

Yesterday Facebook started rolling out the new Timeline features and today Twitter has brought out a new mobile app and will start rolling out the corresponding web UI over the next few weeks

We’ll be rolling out the redesigned Twitter over the next few weeks. You can see it immediately on the just-updated versions of mobile.twitter.com, Twitter for iPhone, and Twitter for Android. You can get early access on your computer by downloading and logging into Twitter for iPhone or Twitter for Android. We’re working on updates for other apps, such as Twitter for iPad, and will share news as they become available.

The iSO app is frankly a very refreshing change. The UX is beautiful, hashtags are bedded into the app under the new Discover tab and the whole app feels much lighter , faster and intuitive.
