I disagree. There is no way in hell that I would want an App on my phone called "Hot Girls" for my boss or mother to find. Nope! It would have to be something hidden on my phone before I would spend a single penny on it.
Not everyone has their boss or mother looking over their shoulder at their phone. And stuff like this is actually pretty tame. It's not actually THAT shameful to have on your phone (admittedly, I wouldn't do it).
Besides, there is a way to have it hidden - have more than eleven pages of apps when you install it.
