URL shorteners like Bit.ly and TinyURL have been thrust into the spotlight thanks to Twitter and its 140-character limit. But while most Twitter applications on mobile or PC incorporate automatic URL shortening, the Twitter.com site itself does not. In March the site introduced URL shortening for direct messages, so that links sent from person to person are wrapped as twt.tl and users are warned of potentially malicious code. Now Twitter is planning to expand this strategy to all tweets so that long URLs get transformed into smaller t.co links.
