4=. Chris Moyles, Broadcaster
His radio ratings may be under pressure, but his Twitter figures are in fine shape. The Radio 1 presenter recently passed the two million follower mark with a possibly tongue-in-cheek tweet referring to himself as the "pied piper of cool". Moyles's Twitter presence is pretty much a companion to his breakfast show; active during the week, sparse at weekends, references to the celeb lifestyle and occasional soliloquies to his beloved Leeds United. For someone who's been embroiled in the odd controversy over the years, Moyles keeps it relatively safe on Twitter; one minor spat with Lord Sugar, but that's par for the course.
