More proof that Lady Gaga is taking over the world: She has her own social network. LittleMonsters.com launched as an invite-only beta site earlier this month, but word about its features has already gotten out. Like Pinterest, LittleMonsters.com allows users to share content, but all Gaga-tinged. It also allows Little Monsters to interact with one another and do whatever it is Little Monsters do in their spare time. Will you join?
