I have been watching Brotherhood 2.0 since January and almost everyday Hank or John says something that makes me smile. John Green is an young adult author and Hank is an environmentalist author/blogger. They committed to each other not communicate via text in 2007 which meant no emails or notes. They've shared their life with people all over the world via their video blog. They asked the world to share their "happy dances" with them...here is the result..."happy dances" from all over the world. I hope it makes you smile or maybe even do a happy dance of your own.
