Of the 8 most recent responses to petitions, I have noticed that President Obama himself has only responded to 1 petition directly.
I, along with others, do not feel that this website has helped much with policy reform.
Having President Obama respond himself would help in making people feel that their voices are being heard by the President, the person they elected, himself, and not just quickly run past him and then delegating someone else to respond.
That is why I propose that each response that reaches the threshold have a response delivered and written by the President himself.
