Thunderclap is a new application that combines the scope of Twitter with the crowdsourcing model of Kickstarter. Users can draft a tweet and, if enough people decide that they agree with its message, have an identical tweet sent by everyone that’s signed their support. Built in New York’s China Town, the app sent its first “thunderclap” yesterday; the company estimates that the ‘clap was viewed by 4 million people.
