We came across a great website today called paywithatweet.com Here is the summary from their site:
In today’s world the value of people talking about your product is sometimes higher than the money you would get for it. ‘Pay with a Tweet’ is the first social payment system, where people pay with the value of their social network.
It’s simple, every time somebody pays with a tweet, he or she tells all their friends about the product. Boom.
It seems like a great concept. We haven’t tried it out yet, but we’re planning on it. We’ll let you know how it goes. Better yet, give it a try yourself. If you’ve all ready tried it let us know your thoughts.
