We believe in the power of petitions to change things for the better. Twitter is the most powerful communication mechanism to spread a message. If we combine both seamlessly only good things can happen. So we create an easier way for twitter petitions. You can sign for a petition without the need to give your e-mail or provide access to your twitter account to external applications. You do it super simply by just re-tweeting the initial petition tweet or make a tweet including a hashtag with the petition identifier.
