Justin Bieber's Twitter presence is almost as prolific as his music. The newly 18-year-old star can make any topic he wants immediately start trending, and his Beliebers will follow him to the ends of the earth (or to anywhere else on the Internet, as it were).

Since the dawn of Instagram, Biebs has been a bigger Twitter influence than ever before.
