Thunderclap is a crowd-speaking platform. Think of it as an online flash mob. You opt in to have a predetermined message posted on you social media at a specified time. Since hundreds of other people will have also opted in and post the message at the same time, the message is more likely to be heard.
We have released a Thunderclap campaign to urge people to back our Kickstarter in its final days. The message will blast out automatically from those who have joined on June 29th at 6pm. Join the Thunderclap with Facebook, Twitter, and/or Tumblr.
