A few months ago, Twitter introduced new profiles so that users could make profiles beautiful and display more style on profile pages. Just upload a header photo on twitter.com. You can make your profile more uniquely yours.
On December 12, this rolled out to all users: You will automatically get the new version of the profile on twitter.com. If you don’t upload a header photo by then, you (and everyone else) will only see a default grey image on your page. Check out this video to see how to make your profile a little more “you”, less generic. The Professsor and SMExperts have made the move.
