I'm not going to make any sweeping judgements about 8 million subscribers. I think blink was probably a staff choice. They're innofensive and have a lot of nostalgia value for anyone over the age of 20. It's not a matter of money, i'm sure a lot of thought went into the decision, or an office poll. Either works.
No way. The people at Blizzcon want to hear a guy say "A bi*ch ni*ga. That's the sh*t I don't like." while exposing his tiny malnourished torso to the crowd.
