Soon, it could be hard to tell if you're on Twitter or Facebook. Twitter is rolling out a big change and will look a whole lot like your Facebook page.
You will notice a larger header and profile picture, popular content will be in larger font, you can pin a tweet to the top of your timeline, and you can have the option to just see tweets with pictures and videos attached.
You may not have the new look yet. It will take a couple of weeks for the rollout to hit everyone.
But, if you start using Twitter today, you will start with the new format.
