Crowd-Funding

A quickie, simple S&A survey; your participation is much appreciated: 

1 - Have you ever contributed to any crowdfunding projects, whether on Kickstarter, IndieGoGo, or elsewhere?

2 - If you have, what encouraged you to contribute? And also, would you contribute again to other projects?

3 - If you haven't ever contributed to a crowdfunding campaign, why haven't you ever done so? And do you think you ever will do so? Or what will it take to encourage you to contribute to a campaign?

That's it!

Thanks!
