Ten years ago, how did you refer to this # symbol? Most people I knew called it the ‘pound sign’ and we barely used it. Except for street addresses (it felt sleeker than the old-school abbreviation “No”) as in #33 Clifford Place.

Ten years ago, we had other things that grabbed our attention. FB had just bragged about 30 million users. Virginia Tech happened, the iPhone had been launched, and the global economy was teetering.

So what were you doing on Aug 23rd, 2007? Where were you working? How did you communicate? I am curious to see how my friends were doing when the hashtag emerged.
