Speaking of disruption, Michael Lopp killed it with this piece:
The reward for winning is the perception that you’ve won. In your celebration of your awesomeness, you are no longer focused on the finish line, you now lack a clear next goal, and while you sit there comfortably monetizing eyeballs, you’re becoming strategically dull. You’ve forgotten that someone is coming to eat you and if you wait until you can see them coming, you’re too late. Just ask Nokia or RIM.
