This recent effort of Lacy's is very irritating. What the hell even qualifies as 'trying to change the world'? Is there some threshold of number of individuals a service must be used by in order for it to be qualified as world changing? They just published an article saying Dropbox has reached 2 million users. Is that not enough? Whether your service is loved by 5 individuals or 500 million, you're changing the way a subset of the world behaves. Let's even forget someone purposefully trying to change the world. Even if your goal is to score it big in the startup scene, your product is going to have to be somewhat useful and appealing to customers. You have to offer some sort of value. So indirectly, you're changing the world in that respect.
