What resources are available to promote a kickstarter project for free?

Question

Marketing

Let's compile a list of resources for free promotion of a crowdfunding project (kickstarter or indiegogo).
Here is my list:
www.kicktraq.com
www.craftpassion.com
www.kickstarterforum.org
crowdfundingforum.com/forum.php
crowdrabbit.com
kickingitforward.org
This is not a list of specialized publications and sites like mashable.com, but purely for starters, project push.
