Thunderclap is a free tool for posting simultaneous messages from lots of different people across multiple social media accounts. Think of it as an "online flash mob." On this podcast, we highlight a few successful Thunderclap campaigns, talk about our own experiences as “crowd-speak” participants, and share ideas for organizing your own Thunderclap.

At Firesteel, we experiment with a lot of new media tools as we advocate for an end to homelessness. The purpose of the Spark Change podcast is to share what we've learned, and to help other advocates use these tools. Visit http://firesteelwa.org/ to learn more and share your feedback.
