You are bound by their whims, however. I feel for you-- it's unfortunate to have something you put your heart and soul into shut down without notice.

This is why I would hesitate before developing a facebook or iOS app. Being subject to the whims of some tech bureaucrat's interpretation is a little too discomforting.

Agree 100%. People have asked for a mobile version of this app, and one of the big reasons I won't do it (or build any mobile app) is because I refuse to invest a lot of time and effort into something that can only be distributed through a 3rd-party channel, with their blessing. I will not take the risk that Apple will not suddenly decide they don't like my app tomorrow. No way.

Android doesn't require the same sacrifices and has a larger market share for free apps.
