Tweetus Commencus! Harry Potter scribe (and avowed fan of good old pen and paper) J.K. Rowling has finally opened her own Twitter account, the Potter site The Leaky Cauldron reported today. So far, Rowling has only tweeted to let everyone know that she’s the real deal and that she probably won’t be posting all that much. So I guess that means we won’t be getting many “magical” updates about her thoughts on Kanye West or how she’s enjoying her Grape Nuts this morning. Regardless, she’s already picked up more than 11,000 followers, a number I expect will balloon upwards quicker than the page count of Goblet of Fire. The real question is how the notoriously prolix Rowling will manage to fit her updates into a mere 140 characters. Ellipsis Continuatum!
