Crazy.<p>Glad to hear that you were able to give back to a very needy community in need on your vacation. As opposed to say, buying a car and naming it after yourself.<p>Can you provide any numbers or statistics on conversion from free to paid? Given there are people on both sides of the fence, do you think it's better to start as paid versions only, or is it better to absorb the cost of the free users and hope they later convert to premium?
