I would have thought it was a foregone conclusion that users were adverse to the standard click-through path on a small modal-use device.
Certainly for a mobile site I won't be using Chitika; instead I'll try another network. The numbers are clear :)
Both those points are pure speculation on my part; data to confirm or refute would be welcome.
