Internet resource: Thunderclap

Thunderclap is a "crowdspeaking" platform that lets individuals and companies rally people together to spread a message. The site uses an "all-or-nothing" model similar to crowdfunding sites such as Kickstarter, in that if the campaign does not meet its desired number of supporters in the given time frame, the organizer receives none of the donations.

On Thunderclap, backers donate tweets and social media posts rather than money.
