That's what I'm getting as I look more into this: It's a colossal waste of time. Maybe if you were on the front end of it, it's fine. But it seems (1) too good to be true (2) really overly dependent on people not up and getting bored. Why waste the time and energy to earn 0.0001 of a bitcoin? And adoption of it as an online payment method doesn't seem widespread enough to justify putting out the energy.
