Jason Fried gave an amazing Web 2.0 Keynote last week. He uses an analogy that we need to be curators of the software we create. If a museum curator takes every painting suggested to him by the users and sticks them all in a room; that creates a warehouse. A curator carefully chooses the paintings that add to his vision and filters out the noise. As software developers we need pick and choose new features carefully. The business and users are a good source of information. We should not take all requirements and blindly implement them into our products.
There is also a great write up from a session given by Jason on Lessons learned at 37 Signals
