Looking thru http://www.thekickbackmachine.com/browse/all/ it appears the projects are overwhelmingly successful. In the first 163 project, just under 75% were successful. Am I interpreting this incorrectly, or are projects funded successfully an overwhelming majority of the time?
According to my numbers, since mid-June 2012, the overall success rate for all projects in all categories has been ~72%. Much higher than Kickstarter's all-time success rate of ~44%. Successes seem to be increasing.
