Interesting launch!

0) Why is this better than MTurk's predefined workflows?

1) How much does it cost?? MTurk charges min(0.005, 10%) for each Human Intelligence Task.

2) How is quality checked???

3) People doing tasks generally report greater satisfaction and generally produce greater accuracy with a smaller topic shift (instead of doing NLP classification about everything at all times, first do topic A, then topic B). I bet you could train a simple classifier to group topics together
