Liam Neeson has a great line in Batman Begins that didn't quite resonate with me until yesterday:
"You haven't beaten me. You've sacrificed sure footing for a killing stroke."
I think this is a great lesson for anyone tempted to monetize a service too quickly and sacrifice adoption and uptake of a product... or to change the direction of your product to take advatage of short term revenue opportunities. Its very easy to pick low hanging fruit, but you also need to "mind your surroundings" and think about whether or not quick payback sets you up to still take advantage of the larger market opportunity.
BTW... I've heard about the possibilities of a sequal to this movie... I'll cast my vote right now for Scarlett Johansson as Harley Quinn should they follow a Joker storyline.
