1) Allow developers to charge monthly/annual subscription pricing. This is possible via IAP, and some apps follow this model, but unfortunately in a world of $.99 apps users just aren't willing to pay a subscription fee for a utility app. 2) Allow developers to track the success of social and internet ad campaigns. I agree that this would be very useful, although again at a price point of $10 or below (minus 30%), all you're going to find out is that your ad campaign has negative ROI anyway. Either way, these suggestions do nothing to prevent developers from getting acquihired if a big company comes along with a big offer - especially if they've previously raised a round of funding. Marco has managed to avoid acquisition because he bootstrapped Instapaper entirely on his own, retains full decision making power, doesn't have investors pushing him for an exit, and hasn't received an offer he's satisfied with (yet). But I would say his situation is probably the exception rather than the norm.
