t.co URL wrapping
In the coming weeks, we will be expanding the roll-out of our link wrapping service t.co, which wraps links in Tweets with a new, simplified link. Wrapped links are displayed in a way that is easier to read, with the actual domain and part of the URL showing, so that you know what you are clicking on. When you click on a wrapped link, your request will pass through the Twitter service to check if the destination site is known to contain malware, and we then will forward you on to the destination URL. All of that should happen in an instant.
You will start seeing these links on certain accounts that have opted-in to the service; we expect to roll this out to all users by the end of the year. When this happens, all links shared on Twitter.com or third-party apps will be wrapped with a t.co URL.
