This magical hashtag journey starts with a nine-year-old.  My youngest son, when he’s not Fortnite dancing, dapping, and playing clash of clans, he loves to use hashtags.  He doesn’t understand what they mean, really, but always seems to use them in a way that makes me laugh, #kidproblems.  What are hashtags all about and how are marketers using the right number in the right place to find new audiences to build their communities organically?
