An open alternative to Kickstarter

angry tapir writes: "Crowd-funding website Crowdtilt officially launched last week, expanding upon the collective fundraising model pioneered by Kickstarter to enable raising money for any project — even a beer blitz. Like Kickstarter, Crowdtilt allows users to create a fundraising campaign with a tipping point. If the effort falls short of the set amount, would-be donors are not charged. However, unlike Kickstarter, the platform allows users to "group fund anything." Users can initiate campaigns without first getting the approval of service administrators, which they must do on Kickstarter."
