No one is quite sure of the origin and no one owns the word, but a “hashtag” is hash mark (#) followed by a word used as a type of bookmark in social media, most notably Twitter. It facilitates cross pollination and collaboration of ideas by creating groupings and words. It creates space in cyberspace where ideas can grow. It is a new word in a world of new words, concepts, and constant change.
