Rumored in February and official today, Twitters profile pages are undergoing a fundamental redesign. Visuals have been growing increasingly important for Twitter and the new design pushes them even further to the fore, with larger background images and more prominent profile pictures. Theres an unmissable similarity to Facebooks profile pages, with the users photos and friends both being tucked into a tile layout on the lower left. Other novelties include a size adjustment to tweets relative to how engaging theyve been — your wittiest one-liners will appear larger in your Twitter feed.
