Life at Hogwarts is pretty old-fashioned. Candles and torches line the walls; servants cook the food and clean the sheets; students pack the library to read ancient, dust-covered books. Isn't it time for the magical world to leap into the 21st century? Isn't it time for Hogsmeade to install Wi-Fi? Isn't it time for Hogwarts students to get online? We wondered about this back in September (pre-Twitter redesign), but with Harry Potter and the Deathly Hallows opening tonight, we thought it a good time to revisit what would happen if laptops, smart phones, and social media came to the Hogwarts School of Witchcraft and Wizardry.
