Smeagol D’Angelo

Just following up, it's also totally Smeagol-like to make people sign up before they can get any useful answers at Quora. True Gollum move, D'gelo. Thanks for showin' yer true colors!

I could see Gollum run around a stage yelling Developers! Developers! Developers! no problem.

Steve Ballmer is Gollum?
