Twitpay.me, is a simple way to send payments up to $1000 via Twitter.  Twitpay will make a note of a promise to make payment and allows the payer to pay using Amazon Payments.Twitpay will also keep a record of that payment until you settle up.One can cancel a “Twitpay promise” by simply clicking the trash can next to a promise when you’re logged in. Of course the honour system is in play but if you want to keep your friends you better keep your promisses right?
