Kickstarter has funded 10,000 projects

"On July 6th, a project called Citizen is releasing a 7” record! from a band in Toledo, Ohio, was funded by 28 backers, becoming the 10,000th successfully funded project in Kickstarter history.
Ten thousand successful projects is a big milestone. Watching projects from every corner of the creative spectrum come to life has been a wonderful thing, and to see what they've accomplished in aggregate is remarkable. Congrats to Citizen and the 9,999 other projects that made their accomplishment possible!
