Almost every founder, engineer, Stanford grad, and VC has been chanting "We're changing the world!" for the last eight years. Stop it. It's trite and annoying and it pisses people off. It doesn't piss people off because your current batch of products are half-baked and stupid. It pisses people off because your very best products of the last decade are, at the end of the day, stupid and trivial and really haven't changed the world in a very positive way. It pisses people off because it doesn't hold water outside the myopic Silicon Valley bubble, where everyone tells each other "We're changing the world" often enough that they actually buy into it.
