The beauty of a hashtag is that no one can control it.
A hashtag is not like a marketing, media, or political message, whose creator thinks it can be created and controlled. It is not like the namespace in domains, on Facebook and Google+, or in trademarks, for anyone can use a hashtag without permission or payment. It’s not like a dictionary with one definition. It’s not like a word on an FCC list that prohibits or chills its use.
A hashtag is open and profoundly democratic. People gather around a hashtag. They salute it and spread it or ignore it and let it wither. They imbue it with their own meaning. The creator quickly and inevitably loses control of it. Jeff Jarvis/Buzz Machine.
