How does it work?
Just paste a link of any length into the Tweet box on Twitter.com. After youve composed your Tweet and you hit the "Tweet" button, we'll shorten the link so that it only takes up 19 characters.
Whats in it for me?
Sharing links on Twitter.com is now simple and instant. Plus, since we show a shortened version of the original link, people will know which site the link points to. This service also increases security. If users click links that are reported as malicious, we direct them to a page that warns them.
What if I want analytics for my links?
You can continue to use your favorite third-party link shortening services.
