A new website called Pay With a Tweet is offering an incredibly simply service '- it allows people to sell things online in exchange for a promotional tweet. In other words, the customer only needs to tweet about the item in question, and they'll be provided with a free download link.
Sound crazy? Once you start to think about it, it's actually incredibly sane. The Pay With a Tweet site lists a number of great applications for this payment method: an aspiring musician selling a new track, a company selling a video of their next viral commercial, a studio selling the trailer for their next blockbuster, or an author selling a teaser of their next book. The beauty of this new service is that it is truly a win-win: the "customer" gets the content for free, and the "seller" gets a free social mention, reaching everyone in the tweeter's social circle.
If you don't have a Twitter account, don't worry; you also have the option of posting to your Facebook profile. Be on the lookout for up-and-coming artists, musicians, and other creative types using this service to promote their work. If you're a creative yourself, give it a try! You might find that 50 people tweeting about your new project and getting it for free might be more valuable then 10 people actually paying for it.
