It's not correct to label this "The Problem with Kickstarter".
It's a rant about how complicated it is to finish hardware projects.
Kickstarter does movies (I didn't know that, I learned it here in the Kickstarter 2012 retrospective), lots of software, comics, publishing, etc.
So please rename to: "The problem with Kickstarter hardware projects" or something.
Kickstarter needs praise and applause because it is great and bringing joy to many backers and founders. Not criticism because one type of project have a 75% failure rate.
