"FYI Liam doesn't have a Twitter and he wants ME to delete mine with good reason."
In a year when Meaghan McCain and even Ashton Kutcher threatened to leave Twitter, Twitter's highest profile defection was tween singer Miley Cyrus. In an Oct. 8 post, she told fans she was deleting her profile on the advice of rumored actor boyfriend Liam Hemsworth — shocking news to her nearly 3 million followers. Cyrus was unrepentant about bailing, telling BuddyTV that she thinks Twitter should be "banned from this universe."
