Kickstarter announced on their blog that their system was compromised and hackers were able to access personal information and encrypted passwords. This definitely means that if you have a login on Kickstarter that you should go and update your password. And if you use that same password on other sites with the same email address, you probably should go update those passwords too. I just wrote about some ways to create unique passwords that are easy to remember, so you might want to check them out and implement you own system.
