2013 social chirpify

Buy with one Tweet. Remember how revolutionary it felt when Amazon introduced 1-Click payments for online shopping? Chirpify takes that concept into the social media era. Sellers offer stuff for sale on Twitter or Instagram (T-shirts, concert tickets, new albums, whatever). You reply with the word "buy" and it's yours. No credit card. No "proceed to checkout" or "add to cart." The entire transaction is conducted through your Twitter account. Apart from buying and selling, Chirpify can also be used for fundraising, giveaways and - most fascinating of all - peer-to-peer payments. Need to pay a buddy back for this morning's coffee? Just tweet "pay" and the amount to his Twitter handle. Chirpify is free to use but takes a 5% cut anytime you get paid.
