Blizzard Entertainment, known for the most well-known and iconic PC games in existence (Warcraft, Starcraft, Diablo, and MMO World of Warcraft, to name a few), is now live on Twitter! These days, lots of folks have Twitter accounts (heck, I've got one), and Blizzard is making their splash into the microblogging/social networking service with some great contests. Here's the info we've been given below:
