Uhhh.... Joe....
Thunderclap is a system that empowers people to promote their favorite causes. By clicking support with facebook, your choosing to opt into posting one time at the day of the thunderclap.
Its a service system, like crowdfunding for social media support.
I agree with you joe... that thunderclap should have a video on it explaining what it means when you click "support with facebook".
It is a little counter intuitive.
You know what, ill send them an email suggesting they add a tutorial for first time thunderclap viewers.
We apologize for any confusion caused. I'll see about making sure we add some context to what thunderclap does the next time we share that link.
I'd love for you to take the time to get to know us a little more Joe.
