Greg Miller (IGN)
You're likely to hear as much about games on Greg Miller's Twitter feed as you are Superman and adorable dogs. IGN's go-to guy for all things PlayStation is as charismatic as they come -- just look at those charming glasses. You'll find little game biz drama surrounding Greg, who's more concerned about linking to cool IGN content and making witty replies to other press folks.
Greg is also one of the most actively involved press folks you'll see in a site's online community. Go ahead, tweet at 'em. He'll reply. In fact, tweet at him all day. Don't stop. Overwhelm him and tell him Mitch sent you.
