It's funny, we make fun of hashtags on social media. The reason why? We don't understand them. We're old. We're not on social media for friends or followers that we don't know. We're not on social media to make money. Well.. a lot of other people are, or even if they didn't start that way, what's the best way to sell your new product? to your friends and family. These things work and people will take notice, you will show up somewhere based on that hashtag and the combined 3 minutes it took you to type #hashie at the end of every post for an entire year will have resulted in increased revenue or exposure(validation).
