Ask HN: Effectively Kickstarter-ing advice?

I got accept to Kickstarter yesterday and I'm working on putting my project together and kicking things off. I've got some ideas I think are good and I've read a lot of relevant material, but nothing beats a second perspective.

What would you make sure to do to be successful on Kickstarter? What would you avoid? Anyone willing to chat briefly, feel free to add me on Skype (minimgroup). For relevance, the project is for a humorous greeting card business. It's no diaspora, but I am passionate about it and want to be effective without "over marketing" to people or appearing manipulative.
