Twitter has a brand new home page. As you can see, popular accounts populate the row of profile pictures in the center of the page, and they've rearranged their sign-up interface to be a little more accessible. A map now extends from left-to-right in the background, and the search bar is clearly visible. Not a huge fan, Twitter. I liked your blue & yellow theme better. Now you look like a consulting firm or a bank.
Not like I ever look at their home page though- I use browsers with cookies. Mmmmm.
