Twitter is to introduce a new feature designed to wrap and shorten all links posted by users, in an effort to improve security and gain more information on links being shared. The t.co service will mean that every link posted on the site, either directly or through APIs and mobile devices, will be shortened and scanned before being posted. Sean Garrett, vice president of communications at Twitter, explained in a blog post that the service will be rolled out during the summer and will provide more insight into posted links. "We want to display links in a way that removes the obscurity of shortened links, and lets you know where a link will take you," he said.
