Quite a nice site too. The banner is faked for now as the promo is over.
Just as a sense check, does anyone believe the reach figures on tweets in case study videos? 24,919,119 people and 545,425,558 Twitter impressions reached from 150,739 tweets? The tweets alone are impressive but the rest of the numbers seem like pulling numbers from the sky.
Chalkbot generated just 36,000 submissions total, so 150,000 tweets, with little reward to the sender, is amazing.
