I think if there is a better way he would have done it. Path of least resistance right? In this case he is a complete stranger and has no social proof so he does what he has to do. Much props to him. Startup is a bitch and this guy gets it done.
I have to give him some respect for getting into YC, but based on everything I've seen, I'm not sure exactly what he 'gets done'. Mostly it seems like bragging and social hacking all the way down.
