Feel the thunder of thousands of people posting the same thing at once!
Definition of Thunderclap as Rachel sees it: A marketing technique wherein authors fill out a campaign on thunderclap to have a simultaneous posting release to Twitter/Facebook/Tumblr. Thunderclap is much like Kickstarter in that you HAVE to have the minimum amount of supporters for the thunderclap to release.
I’m not to my minimum yet and would kindly ask my blog readers to check out my campaign and pledge their support.
