Starting today you can make your presence on Twitter more meaningful with new Twitter profiles. Upload an all-new header photo on mobile apps for iPad, iPhone and Android or twitter.com, and the same image will appear whenever anyone views your profile on the web or these apps. You can upload your header photo, which appears above your Tweets, to express yourself instantly, anywhere.
The mere fact that these updates were announced on NBC's Today Show is all you need to know about Twitter's latest announcements.
Ushering itself into the mainstream media limelight whilst simultaneously culling the lingering remnants of Loren Brichter's vision for Twitter's apps, I can't think of a more fitting way for Twitter to demonstrate quite how far its moved beyond the tech community.
