Kickstarter's existence may be taken for granted in the US, but international users have been unable to launch projects on the site to-date. That will change this fall, when those in the UK will be able to introduce their own ideas onto the site and compete to gain financial backing. The news comes by way of a tweet from Kickstarter, and few details are available at the moment. A 2009 post on the site's official blog says that the service was previously limited to project creators with US mailing addresses and bank accounts because that was the only place where Amazon Payments was available, but that doesn't appear to be a problem any longer since that service recently launched in the UK. The reasoning behind Kickstarter's exclusivity with Amazon Payments is two-fold: the money transfer service is the only one that's able to immediately cancel all charges should a project fail to gain backing and also pay the project creator if he does reach his goal. Of course, users outside of the US have long been able to back projects — the change coming this autumn just means that we'll be seeing quirky, inventive, and massively successful projects that originate from the other side of the pond.
