Jack Dorsey:

A lot of Twitter'’s success has been because it stayed and remained consistent, it increased the ease of communication, and increased the velocity of communication, and people came to it and invented entirely new things, like the "at" symbol in front of a name, which is a behavior that we didn't think of; it's a behavior we saw and we made easier by programming it into the service.

The hashtag, which is a behavior no one in the company thought of, we saw and we made easier.

The retweet. So all these systems were not actually created or invented by us, but by the people using the product and using the service on a daily basis.

And it was just so inspiring to see people take your work and make it theirs, and build something meaningful from it--not just pure products, but actually social constructs as well-and I think that's the true success of what Twitter has done in the world and continues to do in the world.
