I cannot begin to express how much this made me think. In preparation for my own launch coming up, I'm looking at it and wondering why I've spent so much time of Minimum Viable Product when the personality just won't cut it. The guys at Hipmunk posted something to this affect a while ago, but it didn't have the weight of this.
But how does one launch a product with a personality? As a developer, not a designer, I'm at a loss...
