With a lot of fictional characters; from famous ones, such as Homer Simpson, Bender Rodriguez, and Peter Griffin; to the infamous ones, such as Anabelle, Lord Voldemort of Harry Potter, and Herbert the Pervert, fictional characters on social media is increasingly popular, such as those on Twitter. Some are used as an advertising method, while most of them are mostly for fun. And most people who own them are most likely to hide their secret that they own the account. Or, when you see a corporation retweeting fictional character's tweets (i.e. Fox retweeting Homer's tweets), then you will know they own that account.
That's why Twitter, whether they like it or not, will launch a special page where all fictional characters will be placed. This is quite similar to finding people on Twitter, the more traditional way. But in this case, you go to the search bar on top of any Twitter page (in this case, your Home Feed), and then search for any fictional character, in this case, Homer Simpson, and after hovering on the People tab, you see 2 options: Real, or Fictional. Clicking on the Fictional option will let you see Twitter pages of Homer Simpson, even if they're multiple accounts of the same person.
This system also works with searching people as characters in reality shows. In this case, if you search for London Tipton (played by Brenda Song on The Suite Life On Deck), then it searches for the Twitter accounts in the Fictional section with the name "London Tipton" in their name field.
For now, though, the people over at Twitter are still testing this system. CEO Evan Williams had this idea a few months before New Twitter was revealed on Tuesday, September 14, 2010. This new feature is expected to roll out in a few weeks or months. (although, no exact date will be revealed at this time)
