FYI, here is a link to a project (ending in the next 7 hours) on Kickstarter that has been wildly successful.
Part of that success is because of how well the project was presented, the stretch goals and what you get for funding it (plus the quality of the work being produced of course)!

There are many examples of similar, incredibly successful crowd-funded projects. Â This is only the most recent that I’ve been interested in personally (and wish so much to have had the money to back it now).
