One thing I'd like to suggest for your Kickstarter project: Post updates!
I don't know why, but it seems most filkers launch a kickstarter project then never talk to their backers! Ever! Just look at Insane Ian's project, zero comments, zero updates, zero feedback, and he wonders why he almost didn't make it.
So when you do launch a project on any of the crowdfunding sites, please talk to us backers. We get lonely.
