#Hashtag This: How the Twitter Hashtag Caught Fire in San Diego
It’s been over seven years since Chris Messina proposed that Twitter users adopt the hash symbol as a way to collate their discussions and designate groups.
I’m only just now catching up to him, although I have an excuse. I used to be mainstream media.

About the hashtag, Messina was an irresistible force. But Stone, alas, was an immovable object. “He flat out said ‘No.’ But thanks for your enthusiasm,” Messina recalled.
At that time, Twitter was just over one year old. So Messina became a kind of unauthorized Twitter evangelist, encouraging other … Next Page »
